Answer:

x=29. Angle C= 93

Step-by-step explanation:

3(x+2)= 3x+6.

3x+6+52+35= 3x+93.

180-93=87.

87/3= 29. So that means x=29.

for proof you can do 3(29)+93 and you'll get 180.

For angle C; 3(29+2)= 3x31. 31x3= 93.

Angle C= 93 degrees.

MissTica

Answer:

$T > 45$

Step-by-step explanation:

Given

$\frac{T}{3} > 15$

Required

Graph the solution

$\frac{T}{3} > 15$

Multiply both sides by 3

$3 * \frac{T}{3} > 15*3$

$T > 15*3$

$T > 45$
