Question 1:
This question may look complicated, but we have some unnecessary info.
All we need to know that the angle next to y must also be 30 degrees because of alternate interior angles.
Thus, y + 30 = 180
Subtract both sides by 30
y = 150
Question 2:
Angle a must also be 36 because of alternate interior angles.
We also have a triangle.
We know that 36+77+?=139 because of alternate interior angles.
Let's find the ? angle.
? = 26
Now we know that a+b+?=180 because it's a triangle.
36+b+26=180
b=118
That's all we need. The last choice is the only answer that matches these two answers.
(If you want to find the value of c by solving for it, just see that there's a triangle where all the angles but c is known)
Have an awesome day! :)
( 4.625, - 3.75 )
the midpoint of (x₁, y₁ ) and (x₂, y₂ ) is
[
(x₁ + x₂ ), (y₁ + y₂ ) ]
here (x₁, y₁ ) = (5.5, - 4.75 ) and (x₂, y₂ ) = (3.75, - 2.75 )
[ (5.5 + 3.75 ), (- 4.75 - 2.75 ) ]
= (4.625, - 3.75 ) ← midpoint of HX
The answer would be c.lllllllllllllllllllllllll:)
Answer:
A = 78.54cm²
Step-by-step explanation:
A = π r²
D = 2r
A = 
π × d² = × π × 10² = 78.53982cm² = 78.54cm²
I hope this helps. : )
Answer:
x = 27
Step-by-step explanation:
3x-4y = 65
Let y = 4
3x - 4*4 = 65
3x -16 = 65
Add 16 to each side
3x-16+16 = 65+16
3x = 81
Divide each side by 3
3x/3 = 81/3
x = 27
