please help me with this because i don’t understand stand this

Answer 1

Note: complementary angles are two angles whose sum is 90⁰

Answer 2

Answer:

52 degrees

Step-by-step explanation:

Complementary angles have a sum of 90. This means when added they will equal 90. So to solve had the 2 expressions and set them equal to 90.

This looks like, $(2x+18)+(6x-8)=90$. Then, isolate the variable and solve.

• Remove the parentheses

2x +18 +6x -8 =90

• Add like terms

8x +10 =90

• Subtract 10 from both sides

8x = 80

• Divide both sides by 8

x=10

Finally, plug 10 in for x in the expression for angle b. This equals 52 degrees.
