Answer:
220ft^2
Step-by-step explanation:
In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft
In blue: 18ft - 12ft = 6ft
The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3
total rectangle area: 12ft x 18ft = 216
216 - (3 + 3) = 216 - 6 = 200 subtract 6, we added that area in
Answer:
Step-by-step explanation:
Given that in a triangle ABC, AB = 28, BC = 24 and angle C =91,
We have to find measure of angle B.
Since three measurements are given, we can solve the triangle easily
Use the sine formula for triangles.
Since sum of 3 angles is 180, we calculate B easily
Angle B = 180-(A+C)
= 180-(91+58.98)
=30.02
