The sum of the measures of angle M and angle R is 90°. • The measure of angle M is (5x + 10)°.
• The measure of angle R is 55°.
What is the value of x?

The value of x would be 5

Step-by-step explanation:

(for future reference if you have questions like this it’s better to fill in numbers for x to be able to answer the question)

So you want to fill in x with a number. In this case in order for this equation to be right you fill x with 5.

So 5(5)+10=35

And to check your answer to make sure it’s right you would add the measure of angle R which is 55 to the measure of angle M which is 35.

55+35 is 90. Which makes your answer for x correct :) hopefully this makes sense.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

80
