Work out the size of angle x
2 answers:
Answer:
x = 117°
Step-by-step explanation:
First, find the angle the supplements angle 101°.
Using the supplementary angle (angles that add up to 180°).
180° - 101° = 79°
We now have two interior angles inside the triangle, 38° and 79°.
A triangle's total angle measures 180° in total.
So,
? + 38° + 79° = 180°
? + 117° = 180
? = 180° - 117°
? = 63°
Now like the first step we did, use the supplementary angle theorem to find x.
x + 63° = 180°
x = 180° - 63°
x = 117°
Answer:
x = 117 degrees
Step-by-step explanation:
A triangle has 180 degrees in total.
A straight line is also 180 degrees in total.
180 - 101 = 79
Angles inside the triangle
79 + 38 = 117
180 - 117 = 63
63 degrees is the missing angle
x = 180 - 63
x = 117

X/x+9 (original fraction)
x+1/ x+10 = 4/13
x+1=4 so x=3 and x+10=13 so again x=3
now that you have the value of x, substitute it into the original fraction to get:
3/12
