Answer:
20x + 20
Step-by-step explanation:
4(2x+3)+ 4(3x+2)
Expand the brackets.
8x + 12 + 12x + 8
Now simplify.
20x + 20
we know that the shaded side is 90 degrees and we are given 28 degrees
So we add 90+28 and we get 118
Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure
180-118=62
x=62
Your equation is 180=90+28+x
Answer:
d. 6
Step-by-step explanation:
The product of lengths to the near and far intersection points is the same for both secants:
PB×PA = PD×PC
We can use this relation to solve for x, then use the value of x to find PD.
7×12 = (3x)(7x)
4 = x² . . . . . . . . . divide by 21
2 = x . . . . . . . . . . take the square root
__
PD = 3x = 3·2
PD = 6
The two negetive points of the block add thise to you answer
We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion:
