Answer:
a) 5x=8 use a calculator and use distributive property
b) 22=3x+5 -18
22=3x-13
9=3x
x=3
distributive property
c)-48= -8x-20+5x-1
-48= -3x-21
-27= -3x
x=7
distributive property
Step-by-step explanation:
Answer: No
Step-by-step explanation:
This is not an isosceles triangle because there are different angle measurements. The rule of an isosceles triangle is that it must always have two equal sides and angles.
Answer:
The answer for ∠B = 68°
Step-by-step explanation:
Total angle in a triangle is 180° so you can just substract ∠A and ∠C from 180° :
∠A + ∠B + ∠C = 180°
90° + ∠B + 22° = 180°
∠B = 180° - 90° - 22°
= 68°
Evaluate the + ( -) to give - :
Add 2 on both sides:
Evaluate the Right Hand Side:
DIvide by -3 on both sides:
Evaluate the Right Hand Side:
Divide by 4 on both sides:
Simplify to mixed fraction:
