(3x + 5) (10x - 7) find x

The measure of angle TQR is 47 degrees and the measure of angle TRS is 133 degrees

In order to determine the measure of each angle, the value of x has to be determined first

The sum of angles on a straight line is 180 degrees

Thus : (3x + 5)° + (10x - 7)° = 180°

3x + 5 + 10x - 7 = 180

combine similar terms

3x + 10x = 180 - 5 + 7

add similar terms

13x = 182

divide both sides of the equation by 13

x = 14°

Substitute for x in (3x + 5)° and (10x - 7)°

(3x + 5)° = 3(14) + 5 = 47°

(10x - 7)° = 10(14) - 7 = 133°

Step-by-step explanation:

your no able to do this unless you use distributive property or likes terms

the true ones are a b and d

lol.

it's ok we all do this sometimes.
