Answer:

Y = 12         x = 13

Step-by-step explanation:

Triangular Sum says that the three angles in a triangle is 180˙.

So, <DAC + <ACD + <CDA = 180.

1. Substitute the angle measures into the equation above.

<DAC + <ACD + <CDA = 180

(3y + 2) + 52 + 90 = 180

3y + 144 = 180

     <u>- 144   -144</u>

        <u> 3y</u> = <u>36</u>

         3       3

          y = 12

m<DAC &  m<CAB add up tp 90.

2. <DAC + <CAB = 90

         38 + 4x = 90

      <u>- 38 .</u>         <u>- 38</u>

                  <u>4x </u>= <u>52</u>

                   4      4

                    x = 13

70/6 in a mixed number
Arada [10]
6 can go into 70 11 times without having a remainder so the 11 goes on the outside as your whole number. Then you have 4 left over to get to 70 so 4 becomes your numerator. The 6 stays as your denominator. So you have

One mirror is to be in the shape of a triangle whose height is 6 feet less than twice the base of the mirror. If the mirror has
Vlad1618 [11]

Answer:

Base of the mirror is 12 feet and height of the mirror is 18 feet.

Step-by-step explanation:

Given:

Area of the triangular mirror = 108 sq ft.

Let base (b) of the mirror be x.

Now given:

height is 6 feet less than twice the base of the mirror

So we can say that;

Height (h) = 2x-6

We need to find the base and height of the mirror.

Solution:

Now we know that mirror is in triangular shape so we will apply area of triangle formula to find base and height.

Now Area of triangle is half times base times height.

framing in equation form we get;

108=\frac{1}{2} \times x \times(2x-6)\\\\108=\frac{1}{2}\times x \times 2(x-3)\\\\108=x(x-3)\\\\108=x^2-3x\\\\x^2-3x-108=0

Now we will find the roots of x by factorizing the equation we get;

x^2-12x+9x-108=0\\\\x(x-12)+9(x-12)=0\\\\(x-12)(x+9)=0

Now we will solve for 2 values of x we get;

x-12=0\\\\x=12\ ft\\\\Also;\\\\x+9=0\\\\x=-9\ ft

Now we get 2 values of 'x' one positive and one negative.

Since x is base of the triangle which cannot be negative.

so we will discard the negative value.

Hence;

base of triangle = 12 ft

Height of the triangle = 2x-6=2\times12-6 =24-6 =18\ ft

Hence Base of the mirror is 12 feet and height of the mirror is 18 feet.

Solve algebraically: <br> Y = x^2 + 5x - 17 <br> Y = x - 5
Ksenya-84 [330]

Answer:

2

Step-by-step explanation:

What you could do is fill in 2 for the equation and y would equal -3 so for the first one it's like

y= 2^2 + 5(2) -17

y= 4 + 10 - 17 which turns into y= -3

In the second y it would be something like

y= 2 - 5 which would equal y= -3

so x=2
