Answer:
angle A is 94
angle B is 86
Step-by-step explanation:
supplementary angles add up to 180°
(6x + 10) + (4x + 30) = 180
10x + 40 = 180
10x = 140
x = 14
A is 94
B is 86

Answer:
13
Step-by-step explanation:
using c^2 = a^2 + b^2
whereas c is the length of the ladder
a is the top of the ladder
b is the distance from building
so c^2 = 12^2 + 5^2 = 144 + 25 = 169
c = 13
The valley in California has an elevation of feet "below sea level".
Below sea level means below 0 feet, so it'd have -5 feet
The one in Arizona would be lower than it, so the elevation will definitely be -9 feet
To find the area of a triangle, multiply the height (6) by the base (4) and divide by 2.
- 6 • 4 = 24, 24 / 2 = 12.
The area of this triangle is 12.
