This is a isosceles triangle. all sides degrees added together (triangle) is equal to 180.

we know one side is 55°, and since its isosceles, it will be congruent on both sides. so there are 2 55°.

since the sum of all angles is 180°, the equation will be 55°+55°+x=180

combine like terms (55+55), which equals to 110.

last, 180-110 = 70

so the answer will be x = 70°

Step-by-step explanation:

whole number: the set of counting numbers, 1, 2, 3, ..., and includes the number 0.

integer: all whole numbers, zero, and all the negatives of the whole numbers: ..., -3, -2, -1, 0, 1, 2, 3, ...

rational: any number that can be written as a fraction of integers

irrational number: a number that cannot be written as a fraction of integers

1.00 is the same as 1

It is:

A whole number

Can anyone show me the steps in order solve this problem

STatiana [176]

M∠A = 42° [isosceles triangle]

m∠B = 180 - 42 - 42 = 96° [in a triangle, the three interior angles always add to 180°]

m∠C = 180 - 96 - (x+12)
m∠C = 84 - x - 12
m∠C = 72 - x

2x+9 + 3x-1 + 72-x = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 100/4
x = 25

m∠C = 72 - x = 72 - 25 = 47°
