Find the values of x and y.

Mathematics
1 answer:
qaws [65]3 years ago
8 0

Answer:

x=30° y=5

Step-by-step explanation:

All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.

so

8y=40

y=40/8

y=5

Since it's an equilateral triangle. All angles are equal And each angle has dimensions

=180°/3=60°

The angle of the straight line = 180°

so The obtuse angle of the lower isosceles triangle is 180°-60°=120°

The angles at the base of the isosceles triangle are equal

so 2x° = 180°-120°

2x°=60°

x°=60°/2

x°=30°

Given that tan2theta=3/8,what is the value of sec theta
frez [133]
There's an identity 

sec^2 x = 1 + tan^2 x

so here we have

sec^2 theta = 1 + (3/8)^2 =  73/64

sec theta =  sqrt 73 / 8  or  1.068 to nearest thousandth

7+n=−5 18=−3y−6 3/5x=18
Keith_Richards [23]

Answer:

1) n=-12

2) y=-8

3) x= 1/30

Step-by-step explanation:

1) 7+n=-5

7+n-7=-5-7

n=-12

2) 18=-3y-6

  -3y-6=18

 -3y-6+6=18+6

 -3y=24

 -3y/-3 = 24/-3

      y= -8

3) 3/5x=18

   3/15 X 5x= 18 X 5x

        3=90x

    90x/90= 3/90

        x= 1/30
