A: 71+19=90 Complementary: angles add to 90
Answer:
n = 23°
Step-by-step explanation:
Angles that form an "x" shape are called vertical angles.
In this case, ∠MRP and ∠ QRN are vertical angles.
Vertical angles are always equal.
Therefore, m∠MRP = m∠QRN
Substitute
m∠MRP = m∠QRN
35° = 2n - 11°
Add 11° to both sides of this equation
46° = 2n
Divide both sides of the equation by 2
23° = n
n = 23°
Hope this helps :)
Answer:
4cm
Step-by-step explanation:
The area of the base will be doubled 60
to 120
3/5=12/x
reciprical of both sides
5/3=x/12
times twelve on both sides
x=20
