Solve for the measure of angle 7

Mathematics
1 answer:
Verdich [7]3 years ago
7 0

Answer:

7 is 35°

Step-by-step explanation:

The measure of an exterior angle is equal to the sum of opposite interior angles.

So 4x - 80 = x + x - 10

4x - 2x = 80 - 10

2x = 70 , x = 35°

Hence 7 is 35°

icang [17]

Answer:

Step-by-step explanation:

f(x)=-2x+4\\g(x)=2x^2-2x-8\\(g\circ f)(x)=g(f(x))\\=g(-2x+4)\\=2(-2x+4)^2-2(-2x+4)-8\\=2(4x^2-16x+16)+4x-8-8\\=8x^2+(-32x+4x)+(32-8-8)\\=8x^2-28x+16

ruslelena [56]

Answer:

<h3>           m∠BAC = 80° </h3>

Step-by-step explanation:

m∠BCD = 145°  ⇒  m∠BCA = 180° - 145° = 35°

From ΔABC:

                    m∠ABC + m∠BCA + m∠BAC = 180°

                         65° +  35° + m∠BAC = 180°

                                  m∠BAC = 180° -  100°

                                   m∠BAC = 80°

Help plz I'm desperate ​
lutik1710 [3]

<u>Anna:</u>

1st month = 18 + \frac{3}{4} = 18\frac{3}{4} inches

2nd month = 18\frac{3}{4} + \frac{3}{4} = 19\frac{1}{2}

3rd month = 19\frac{1}{2} + \frac{3}{4} = 20\frac{1}{4}

4th month = 20\frac{1}{4} + \frac{3}{4} = 21

5th month = 21 + \frac{3}{4} = 21\frac{3}{4}

<u>Grace:</u>

Because Anna is \frac{9}{4} inches shorter than Grace, we can start the count from the third month:

1st month = 20\frac{1}{4}

2nd month = 21

3rd month = 21\frac{3}{4}

4th month = 21\frac{3}{4} + \frac{3}{4} = 22\frac{1}{2}

5th month = 22\frac{1}{2} + \frac{3}{4} = 23

Need some help please would really be greatful
Gnesinka [82]

Answer:

x = 100°

Step-by-step explanation:

Actually the drawing is very inaccurate, so it is a regular pentagon, otherwise x would be 60° and none of the answers would fit.

The formula for finding the sum of all angles in a polygon is:

(n-2) * 180°

n is the number of sides

Here n = 5, so the sum of all angles is (5-2) * 180° = 540°

x + 2x + 86 + 92 + 62 = 540

3x = 300

x = 100
