For this, we will be using the pythagorean theorem, which is 
. Since we have the hypotenuse and one of the legs, we can solve for the other leg. Our equation will look like this: 
Firstly, solve the exponents: 
Next, subtract 3600 on both sides: 
Next, square root both sides, and your answer will be x = 80 units
Answer:
a) x=5
b) x=6
Step-by-step explanation:
a)
3x+7=180-(10x-22)
3x+7=202-10x
13x=195
x=5
b)
11x-3=4x+39
7x=42
x=6
I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.
Answer:
B
Step-by-step explanation:
Answer:
13- 60, 14- 30
Step-by-step explanation:
number 13 is a 60, 60,60 triangle
number 14 has two identical edges 2 of the corners are the same:
30, 30, 120
Answer:
16
x=16
Step-by-step explanation:
divide both sides of the equation by 5
on the left side of the equation, any expression divided by itself equals one and on the right side of the equation 80÷5=16 so x=16
