Answer:
∠
°
Step-by-step explanation:
- The cosine of an angle is equal to the side adjacent to the angle over the hypotenuse, the longest side.
- We need to find the hypotenuse of this triangle. This is relativly easy to do with a right triangle; we can just use the Pythagorean Theorem.
- Pythagorean Theorem:
where 
, 
, and 
are the 3 different sides of a right triangle.
- Our hypotenuse is
. Now we can finish solving for ∠
.
∠°
Subtract 14 from 90 then find out what adds up to get to 76 then put down what you want that is how I was told how to do
Answer:
Since the ray bd is bisecting the angle abc, equate 3x + 4 to 7x - 20.
Step-by-step explanation:
3x + 4 = 7x - 20
x = 6
.. Therefore, angle abc = 3x + 4 + 7x - 20
= 18 + 4 + 42 - 20
= 44
