Answer:
x=20
Step-by-step explanation:
By the Triangle Sum Theorem, the angles of a triangle add up to 180. So we can set up the equation like this:
2x-10+70+4x=180
Combine Like terms
6x+60=180
Subtract 60 from both sides
6x=120
Divide by 6 to isolate the variable
x=20
Answer:
Step-by-step explanation:
Construction: To copy angle CAB.
i. On angle CAB, with center A and any radius; draw an arc to intersect CA at E and AB at F.
ii. Place a divider at EF to copy the angle.
iii. Draw a separate straight line MN of approximate length to AB.
iv. Mark point P on MN. Place the divider with radius EF at P to mark Q.
v. Draw a line LM from M through Q.
vi. Therefore, angle CAB would be equal to angle LMN.
Im pretty sure its like this
3,440,621. Srry if its wrong..
Answer:
angle C = angle E. that my answer
Answer:
The radius of the semicircle is 4 cm
Step-by-step explanation:
The diameter of the semicircle is 8 cm
The radius is 1/2 of the diameter
1/2 *8 = 4 cm
The radius of the semicircle is 4 cm
