what is the value of x?
a.
73°
b.
45°
c.
35°
d.
25°

x = 35

Step-by-step explanation:

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

Subtract the sum of the 2 base angles from 180 for angle at vertex

vertex = 180° - (73 + 51)° = 180° - 124° = 56°

The vertex angle is composed of x and 21, so

x + 21 = 56 ( subtract 21 from both sides )

x = 35

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
