Answer:

76

Step-by-step explanation:

The sum of the angles of a triangle add to 180

3x+10 + 2x+20 = 140

5x+30=140

-30       -30

5x=110

x=22

3*22=66+10=76

Answer:

76

Step-by-step explanation:

The sum of the angles of a triangle add to 180

40+ 3x+10 + 2x+20 = 180

Combine like terms

70 + 5x = 180

Subtract 70

70+5x-70 =180-70

5x = 110

Divide by 5

5x/5 = 110/5

x = 22

We want to find BCA

BCA = 3x+10

        = 3(22)+10

        = 66+10

         =76

Please help ASAP THIS IS MY FINAL QUESTION!!!! 20 points!!!!
givi [52]

Answer:

y= 1/2x-3

Step-by-step explanation:

2y - x = 8

First find the slope

2y = x+8

Divide by 2

2y/2 = x/2 +8/2

y = 1/2 x +4

The slope is 1/2  ( y=mx+b where m is the slope and b is the y intercept)

When lines are parallel they have the same slope)

Using y = mx+b

y =1/2x+b

Substituting the point (4,-1) into the equation

-1 =1/2(4)+b

-1 = 2+b

-3 =b

The equation of the line is

y= 1/2x-3

A soccer player uses her head to hit a ball up in the air from a height of 2 meters with an initial vertical velocity of 5 meter
Mandarinka [93]

Answer:1.32 s

Step-by-step explanation:

Given

The initial height of ball H=2 m

Initial velocity u=5 m/s

Height of ball at any instant is given by

H=-4.9t^2+5t+2

The ball will hit the ground when h=0

-4.9t^2+5t+2=0\\4.9t^2-5t-2=0\\t=\dfrac{5\pm\sqrt{25+4(4.9)(2)}}{2\times 4.9}\\t=\dfrac{5\pm\sqrt{64.2}}{9.8}\\t=\dfrac{5+8.01}{9.8}=1.32\ s\quad\text{Neglecting negative value of t}
