Can anyone help? Thanks in advance. From a point on the crater floor, you run ropes to the ends of the tunnel. The first rope's distance covered is The two ropes meet at an angle of 68 degrees. The two roads meet at an angle of degrees. A telephone company wants to place a cable that connects Westville and Eastville directly. The beach slopes gently at an angle of 3 feet from the horizontal. Laying at the water's edge, 50 feet from the base of the cliff, you determine your position, and a straight line to the top of the cliff creates an angle of 70 degrees with the line to the base of the cliff.

She measures feet between two points on the valley floor next to the cliff and sights the top of El Capitan at the angles shown. From a point on level ground, they measure and angle of elevation to the top of 21 degrees. They move meters closer and the angle is now 35 degrees. The 1st balloon is 12 miles from the airport and the second balloon is 17 miles from the airport. The observed angle between them is 70 degrees. I really appreciate any help. Jan 5, 2, Germany.

Engage your students with the circuit format! This question circuit asks students to draw triangles based on given information, and asks them to find a missing side or angle.

There are also two word problems towards the end. Technology use scientific calculator is required on all questions. I wrote this circuit as a request for an accelerated geometry teacher, but if can definitely be used in algebra 2, precalculus, trigonometry, or as ACT prep. You will love the sounds of your students working in this format!

Mine do not get up when the bell rings. I do not include answer keys with my circuits since the answers are embedded in the circuit it is how the students move from one question to the next in a scavenger hunt manner. The only prep the teacher needs to do is work the circuit ahead of the students. Let the circuit take care of the rest!

Only then will we be able to find which answer choice is NOT an angle. Using the Law of Cosines we are able to find each angle. The answer choice that isn't an actual angle of the triangle is. We can solve for C the same way, but since we now have A and B, we can use our knowledge that all interior angles of a triangle must add up to to find C. We are only given sides, so we must use the Law of Cosines.

The equation for the Law of Cosines is. We have three known sides and three unknown angles, so we must write the Law three times, where each equation lets us solve for a different angle.

What is the measurement of? Round to the nearest tenth, if needed. Then simplify. Solve and then round to the appropriate units:. Find the measure, in degrees, of the largest angle in a triangle whose sides measure, and. Since 10 is the largest side length, it is opposite the largest angle and thus should be the c-value in the equation below. Use the Law of Cosines to find.

It will vary depending on your rounding. Note: we use the "approximately" to indicate that the answer is around 9. The 2 sides of a triangle have lengths of 10 and The included angle is 25 degrees. What is the length of the third side to the nearest integer? Substitute the known values and solve for. Round to the nearest tenth. Then take the square of both sides:. Finally, round to the appropriate units:.

Synthetic division. Logarithmic problems. Simplifying radical expression. Comparing surds. Simplifying logarithmic expressions. Negative exponents rules.Use the Law of Sines to find. Notice that we did not use. In order to solve this problem, we need to find. Looking at the triangle, we know c, C, and B. We can either solve for side b, using the law, or angle A using our knowledge that the interior angles of a triangle must add up to be Solve for. Round to the nearest tenth.

Therefore, after rounding to the nearest degree. Find the length of the missing side. First, use the Law of Sines to find the measurement of angle. Now, use the Law of Sines again to find the length of.
