Answer : x= -4
This type of problem, you set them equal to each other. And then solve. Don’t forget you can multiply each side by denominator to eliminate the fraction.
Work:
We know that all three angles in a triangle must add to 180 degrees so we can use this fact to find the measure of the missing angles.
180-57-101= 22 degrees
180-72-72=36 degrees
180-x-20=160-x degrees

Hello! So...
We are given the following:
Solve for x.

====================
1. Group the like terms.
====================
2. Add similar elements (
).
====================
3. Subtract 23 from both sides.
====================
4. Simplify.
====================
5. Divide both sides by 4.
====================
6. Simplify.
(aka. Option A)
====================
Hope this helps!
Answer:
b = 
Step-by-step explanation:
Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.
Thus, to determine the value of b;
Sin θ = 
Sin b = 
= 
= 0.38462
⇒ b =
0.38462
= 22.6202
b = 
The measure of angle E (= b) is
.

Answer:
12/16, 6/8, 15/20, 24/32
Step-by-step explanation:
Because to find the equivalents, you have to multiply/ divide the numerator and the denominator with the same number.
