The measures of the angles of a triangle are shown below. find the value of x.

79°, 70°, x°

The sum of the three inside angles of a triangle need to equal 180 degrees.

X = 180 - 79 - 70

x = 31 degrees.

The third angle is 31°

Step-by-step explanation

Step one:

Given first and second angles to be

79° and 70° we need to find x

Step two : the sum of angles in a triangle is 180°

X°+79°+70°=180°

X= 180-70-79

X is 31°

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
