We know that AB is perpendicular to CD. (that was given)
Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.
180+180=360
90*4=360 See the similarities?
7x+6= 90 degrees
Subtract 6 on both sides.
7x=84
Divide both sides by 7.
x=12
"B" is the correct answer.
I hope this helps!

The Associative property of addition is where you group the numbers differently with parenthesis. That equation could be written as (8+6) + 7 = 21 or (7+8) + 6 = 21
All you have to do is regroup the numbers
I dont know exactly what your asking but 145% of 24 is 34.8
and 24% of 145 is 34.8
i guess they came out the same lol
Answer:
The correct options are a,b.
Step-by-step explanation:
The area of sector of a circle equals
Area of a sector = 
where
is the angle subtended at the center by the sector
is the radius of circle
This indicates that area of the sector depends on:
1) Radius of circle
2) Angle subtended at the center by the sector
3) Area of sector does not depend on pi.
Also if we know the area of the sector only we cannot calculate area of area of whole triangle as we need one more information either angle of the sector and vice versa.
Answer:
30cm3
Step-by-step explanation:
Volume=Base area *height
Base area is a triangle=1/2 *base*height
1/2*3*4=6cm2
Height=5cm
Volume=6*5=30cm3
