Answer:
12
Step-by-step explanation:
triangle on left= 2 cuz 2 times 2=4 /2 =2
and same thing with right
then middle it just 2 times 2
ALWAYS REMEMBER DIVIDE THE TRIANGLES BY 2
Answer:x = 45
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees. The angles in the given triangle are
Angle p is 25
angle r is 20
angle q is 3x
Therefore,
Angle p + angle r + angle q = 180
25 + 20 + 3x = 180
45 + 3x = 180
Subtracting 45 from the left hand side and the right hand side of the equation, it becomes
45 - 45 + 3x = 180 - 45
3x = 135
Dividing the left hand side and the right hand side of the equation by 3, it becomes
3x/3 = 135/3
x = 45
