Answer:
the missing angle will be 140°
Answer:
Step-by-step explanation:
69 + 15h = 39h
69 = 39h - 15h
69 = 24h
69/24 = h
2.875 hrs <======
69 + 15(2.875) = 39(2.875)
69 + 43.125 = 112.125
$ 112.125 = $ 112.125 <====
I didn't round anything.

All you have to so is divide 1968 by 4.
1968 ÷ 4 = 496.5 = 1/4
Now multiply 496.5 by 3 = 1, 489.5 = 3/4
I hope this helps! :_
Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
