1) Angle mnq is equal to angle q plus angle n (because two interior angles equal one exterior angle)

2) 132= 54 plus angle n

3) 180-132=48 (angles on a straight line equal to 180 degrees)

3x+102=180

3x= 78

x is 26 degrees

Answer both question for 20 points and brainliest

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

$V=\frac{1}{2} bhl$

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct

One angle be x

other is 2x-6

ATQ

$\\ \sf\longmapsto x+2x-6=90$

$\\ \sf\longmapsto 3x-6=90$

$\\ \sf\longmapsto 3x=96$

$\\ \sf\longmapsto x=32$

$\\ \sf\longmapsto 2x-6=2(32)-6=58°$

If f(x) = 7x- 6, which of the following is the inverse of kx)?

Yanka [14]

Step-by-step explanation:

$f(x) = 7x - 6$

$\:$

<u>Inverse</u>

$y = 7x - 6$

$x = 7y - 6$

$x + 6 = 7y$

$y = \frac{x + 6}{7}$

${f}^{ - 1} (x) = \frac{x + 6}{7}$
