In triangle abc the measure of angle a is 2x +3, the measure of angle b is 4x+2, and the measure of angle c is 2x-1. what are the measures of the angles

see explanation

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

Summing the 3 angles and equating to 180 gives

2x + 3 + 4x + 2 + 2x - 1 = 180

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22

∠A = 2x + 3 = (2 × 22) + 3 = 44 + 3 = 47°

∠B = 4x + 2 = (4 × 22) + 2 = 88 + 2 = 90°

∠C = 2x - 1 = (2 × 22) - 1 = 44 - 1 = 43°

e) none of the above because the measure of angle cba is 101°

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
