Answer:
X = 12
Step-by-step explanation:
If the angle depicted on top is the angle for the inside angle in the triangle, we can find x easily. a line is 180 degrees so we can do 180-151 for the right inside angle. that's 29. we can do 5x+3+9x-20+29 = 180. 14x+12=180. 14x = 180-12. 14x = 168. 168/14 = 12
The given equation is
And we have to solve for y.
Solving for y, means isolating y . And to isolate y, we need to get rid of 4 that is with y .
It means we have to separate 4 from y, and for separation , we have to perform division. That is, we have to divide both sides by 4, and that will be the next step .
So out of the four options, correct option is the last option .

convert your percentage into a decimal: 20% converts to 0.20
then, just multiply 0.20 with 70. you should get 14.
Answer:
D
Step-by-step explanation:
x + 5 + 3x + C = 180 All triangles have 180 degrees.
4x + 5 + C = 180
But C must be equal to 3x. Notice the markings on the lets of the triangle.
4x + 5 + 3x = 180
7x + 5 = 180 Subtract 5 from both sides
7x = 180 - 5
7x = 175
x = 25
But angle C = 3x
C = 3*25
C = 75
Answer:
c = 10
Step-by-step explanation:
The pythagoras theorem :
a² + b² = c²
a = 6 and b = 8
6² + 8² = c²
36+64 = c²
100 = c²
c = √100
c= 10
