This is what I found

Step-by-step explanation: <em>If you look at the figure, the angle marked red is equal to 70° because vertical angles are equal. So, that also means that the opposite angle 2 is also 70°. So, the first equation is:</em>

<em />

<em>70 = 5x + y</em>

<em />

<em>Next, the green angle as marked is equal to</em>

<em>Green angle = 180 - 70 = 110</em>

<em>Being vertical angles, angle 1 is then equal to 110°. So,the second equation is</em>

<em />

<em>110 = 5x + 3y</em>

<em />

<em>Subtract the two equations:</em>

<em />

<em>    5x + y = 70</em>

<em> -  5x + 3y = 110</em>

<em>________________</em>

<em>           -3y = -40</em>

<em>              y = -40/-3 = 13.33°</em>

<em />

<em>Substituting y to either one of the equations,</em>

<em>5x + 13.33 = 70</em>

<em>Solving for x, </em>

<em>x = 11.33°</em>

<em />

PLEASE HELP FAST!!! Find the surface area of the composite figure. Round your answer to the nearest tenth if necessary.
aksik [14]

Using the surface area formula for rectangular and triangular prism, the surface area of the composite figure is: 444 m².

<h3>What is the Surface Area of the Composite Figure?</h3>

Total surface area = surface area of the top triangular prism + surface area of the bottom rectangular prism - area of the surface both share together.

Surface area of the top triangular prism = (S1 + S2+ S3)L + bh = (10 + 10 + 16)5 + (16)(6) = 276 m².

Surface area of the bottom rectangular prism = 2(wl + hl + hw) = 2·(5·16+4·16+4·5) = 328 m²

Area of the surface both share together = 2(16)(5) = 160 m²

Total surface area = 276 + 328 - 160 = 444 m².

(x^2y^3) = (xy^a)^b
Rainbow [258]

Answer:

C. \frac{3}{2}

Step-by-step explanation:

To find the value f b, we need to compare the exponents.

The given exponential equation is:

( {x}^{2}  {y}^{3} )^{3}  = ( {x}  {y}^{a} )^{b}

Recall and apply the following rule of exponents.

( {x}^{m}  )^{n}  = {x}^{mn}

We apply this rule on both sides to get:

{x}^{2 \times 3}  {y}^{3 \times 3} =   {x}^{b}  {y}^{ab}

Simplify the exponents on the left.

{x}^{6}  {y}^{9} =   {x}^{b}  {y}^{ab}

Comparing exponents of the same variables on both sides,

b = 6 \: and \:\: ab = 9

\implies \: 6b = 9

Divide both sides by 6.

b =  \frac{9}{6}

b =  \frac{3}{2}
