29 percent = 29/100
So 29/100 x 20
= 5.8
Answer/Step-by-step explanation:
Given:
C = right angle = 90°
BC = a = ?
AB = c = 12
AC = b = 9
Required:
a, <A, and <B
Solution:
✔️Find a using Pythagorean Theorem:
a = √(c² - b²)
a = √12² - 9²) = √63
a = 7.93725393 = 8 (nearest whole number)
✔️Find A by applying trigonometric ratio:
Thus,
Reference angle = A
Hypotenuse = 12
Adjacent = 9
Therefore,
m<A = 41° (nearest whole number)
✔️Find B:
m<B = 180 - (90 + 41) (sum of interior angles of triangle)
m<B = 49°
Answer:
y = 25.
Step-by-step explanation:
PQ and RQ and SQ are congruent so
x + 10 = 2x - 5
15 = x.
So PQ = 15 + 10 = 25.
But PQ = RQ = y, so
y = 25.
If they started at the south pole every direction is north. Traversing the lattitudes (traveling 20 miles west) doesn't get you any farther from the pole.
So they photographed south pole stuff, mostly snow.
