Answer:
x=40
Step-by-step explanation:
so the angle opposite the 20º angle must also be 20º
this means that because 20º and 2 2x's are all on one straight line they must add up to 180
so 180=20+2*2x
160=4x
x=40
Answer:
-8
Step-by-step explanation:
-12r+4=100
100-4=96
-12r=96
96/-12=-8

Answer:
Please check the explanation!
Step-by-step explanation:
Given the attached graph below, it is clear that the right angle triangle ABC is shown.
Here are some of the information we can get from the right angle triangle ABC such as:
We have to determine the unknown side 'x' using the trigonometric ratios
As
tan Ф = opp/adjacent
From the diagram it is clear that
Ф = 30°
opp=8
adjacent = BC = x
so
tan Ф = opp/adjacent
tan 30 = 8/x
1/√3 = 8/x
x = 8×√3
x = 13.9
Therefore, the missing length will be: x = 13.9
