A) angle A = 180-135= 45 degrees
Angles A and 135 are supplementary angles
b) angle B= 135 degrees
because the two 135 angles are vertical angles ( opposite angles made by two intersecting line)
c) angle C = 45 degrees
because angles C and angles A are corresponding angles since line (1) and line (2) are parallel
Answer: 8.1ft
Step-by-step explanation:
It may help to draw it out but for this question you would have to use pythagoras' theorem.
The formula for the shorter side is a²=c²-b²
The height of this triangle is 4ft (b) and the hypotenuse (the diagonal that stretches from the top to the bottom) is 9ft (c).
When we put the numbers in the formula you get a²=9²-4²
9²=81
4²=16
a²=81-16
a²=65
Then because we want to find a on it's own you would have to square root 65 which is 8.1 (to the nearest tenth)
Tip: Before finding a volume, you'll need to know the FORMULA of it. So the formula for a volume is Length x Width x Height. Then you should be able to solve any shape.
Answer:
z = 5
x = 0
x = 1
Step-by-step explanation:
(z - 5)x^2 - (z - 5)x = 0 Take out z - 5 as a common factor
(z - 5)(x^2 - x) Take out x as a common factor
(z - 5)(x)(x - 1) Any one of these could equal 0. There are 3 solutons.
z - 5 = 0 Add 5 to both sides
z - 5 + 5 = 0 + 5
z = 5
===============
x = 0
===============
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
