Answer:

Angles 1, 4, and 7

Step-by-step explanation:

This is because angle 1 and the angle with 27 degrees are opposite angles and angle 4 because it is a corresponding angle, and because of angle 4 angle 7 because angles 4 and 7 are opposite diagonal angles

Answer:

(y+1)

Step-by-step explanation:

use quadratic formula.

you will get two values of y

y= 7/5 and y= -1

u can create factors using these values of y (making 0 subject)

for 7/5

7/5=y

7=5y

5y-7=0

zero becomes subject in such cases bcz there are no numbers left on that side

now for -1

-1=y

y+1=0

so your factors are 5y-7 and y+1

The triangles are NOT similar.

If they were the ratios of the sides would be the same.

The function A(b) relates the area of a trapezoid with a given height of 10 and

Natali [406]

Answer:

$B(a)=\frac{a}{5} -7$

Step-by-step explanation:

The input it taken as the unknown base value, while the output here is the area of the trapezoid. b is therefore the base value, and A( b ) is the area of the trapezoid. Let's formulate the equation for the area of the trapezoid, and isolate the area of the trapezoid. To find the inverse of this function, switch y ( this is A( b ) ) and b, solving for y once more, y ➡ y ⁻ ¹.

y = height $*$ ( ( unknown base value ( b ) + 7 ) / 2 ),

y = 10 $*$ ( ( b + 7 ) / 2 )

Now switch the positions of y and b -

b = 10 $*$ ( ( y + 7 ) / 2 ) or $b=\frac{\left(y+7\right)\cdot \:10}{2}$ - now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a,
