Please help; with an explanation to these please

Step-by-step explanation:

using supplementary angles we can fine that two angles of a straight line =180

128+?=180 ?=180-128=52

126+?=180 ?=180-126=54

all angles of a triangle add up to 180 degrees

180=52+54+?

94=?

180-94=x

106=x

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

see the picture for the graph.
