You have to add 23 and 45 will get 68 then divide 68 by 4 and that is your answer
Answer:
41 degrees to the nearest degree.
Step-by-step explanation:
A line drawn from the vertex and bisecting the base forms 2 right triangles.
The base of one right triangle = 1/2 * 12 = 6 m.
So cos A = adjacent side /hypotenuse where A is the angle of inclination.
cos A= 6 / 8 = 0.75
m < A = 41.41 degrees.
Answer:
If two triangles Δ RST and Δ XYZ are similar, then corresponding angles are equal and their corresponding sides are proportional.
So here ∠R=∠X, ∠S=∠T and ∠T=∠Z
To solve this problem, you need to use the Exterior Angle (Out) equation which for this problem would be
. After correctly solving the problem with this equation, you will figure out that the answer is 79.
mHJ= 79°
Hope this helped :)
