Answer:

(13) Equation: x + (x+2) + 72 = 180

Answer: x = 53

(14) B = 55 degrees

Step-by-step explanation:

(13) The sum of the angles in any triangle is always 180 degrees, so you can find the sum of the given angles and set up an equation, then solve

x + (x+2) + 72 = 180

2x + 74 = 180

2x = 106

x = 53

(14) If x = 53 and angle B is equal to to x + 2, you can just add 2 to 53 and get the answer that the measure of angle B is 55 degrees

Rom4ik [11]

Answer:

Step-by-step explanation:

We are required to evaluate:

0.1m+8-12n

When $m=30, n=\frac{1}{4}$

Substituting these values into the expression, we have:

$0.1m+8-12n=0.1(30)+8-12(\frac{1}{4})\\=3+8-\frac{12}{4}\\=3+8-3\\=8$
