Answer:
The third angle of the triangle is 70°.
Step-by-step explanation:
The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.
We have to find the third angle.
Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.
Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}
⇒ 30° + 80° + ∠ C = 180°
⇒ ∠ C = 180° - 30° - 80° = 70°
Therefore, the third angle of the triangle is 70°. (Answer)
I believe the answer is 1 1/2 / minute
Width= x
Length: 80+x
p=2(l+w)
320=2(80+x+x)
320=2(80+2x)
320=160+4x
320-160=4x
160=4x
160/4=x
40yd=x
The width is 40 yds and the length is 80+40=120 yards
Hope I helped :)
If you mean "Who's" good at area of rectangles then yes I am.... It's just the base of the rectangle times the height and that will give you the area.
