Answer:
1/2
There are three numbers above 3
And there are a total of 6 sides
Thus giving us 3/6
Simplify to get 1/2
Answer:
a) Angle 1: 80°
Angle 1 = Angle 5
(corresponding angles)
Angle 5:
180 - 100 = 80°
Supplementary angles
b) Angle 8: 80°
Angle 8 = 180 - Angle 6 = 180-100 = 80
(Supplementary angles)
c) Angle 2: 100°
Angle 2 = Angle 6
(Corresponding angles)
For following directions, just rotate the pic accordingly
Perpendicular lines have a slope that is the opposite reciprocal of the given slope. This means the new slope is -2.
Then you plug in the point to get your new y intercept 10=(-2)7+b
You solve by first multiplying -2 and 7 to get 10=-14+b
Then you add 14 on both sides to get 24=b
You plug this into the equation with your new slope to get y=-2x+24
Answer:
Step-by-step explanation:
Given
varies directly with 
This means
∝
This can be written as:
where 
is the constant of proportionality.
We know that when 
then 
. Using this we can find value of .
so, we have
Dividing both sides by 8 to isolate .
∴ 
when 
then will be
∴ 
(Answer)
Answer:
The hight length : h
The base length : a
Apply the Pythagorean theorem in the right triangle :
h² = 13² - (10/2) = 144
h = √144 = 12 cm
S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²
