Find the measures of the angles of each triangle (in degrees) and classify the triangle as acute/right/obtuse and scalene/isosceles/equilateral (one from each triple) A=5x - 10 B = 3x C= 2x - 10

Step-by-step explanation:

given :

A=5x - 10

B = 3x

C= 2x - 10

solution:

A+B+C = 180°

5x - 10 + 3x+ 2x - 10 = 180

10x -20 = 180

10x = 200

x = 20

A = 5(20)-10 = 100-10 = 90°

B = 3x = 3(20) = 60°

C = 2x-10 =2(20)-10 =40-10 = 30°

this is the right triangle and scalene triangle

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
