What is the value of h?

Mathematics

algol [13]3 years ago

The two angles shown are supplementary angles, meaning that there sum equals 180. Knowing this you can set up an equation and solve for h...

3h + 18 + 15h = 180

Combine like terms

18h + 18 = 180

Subtract 18 to both sides

18h + (18 -18) = 180 - 18

18h = 162

Isolate h by dividing 18 to both sides

18h/18 = 162 /18

h = 9

Hope this helped!

9 times the sum of b and 2 is 8
Ksivusya [100]

I suppose you want to solve the following equation for b:

9(b+2)=8

First of all, you need to divide both sides by 9:

b+2 = \dfrac{8}{9}

Then, subtract 2 from both sides:

b = \dfrac{8}{9}-2 = \dfrac{8}{9}-\dfrac{18}{9} = -\dfrac{10}{9}

IS THERE ANYONE GOOD AT MATH AND FINDING ROOTS ON GRAPHS THAT CAN HELP ME PLZ ??????
elena-s [515]

Answer:

Step-by-step explanation:

A root is a value for which a given function equals zero. When that function is plotted on a graph, the roots are points where the function crosses the x-axis. For a function, f(x) , the roots are the values of x for which f(x)=0 f ( x ) = 0 .

Find the area of the geometric figure.<br> 3 yd<br> 3 yd<br> Traperoid<br> 7 yd
Reika [66]

Step-by-step explanation:

The question isn't clear, so I'll just give you a formula to find the area of trapezoid,

(a+b)*h/2, where a = base side, b = top side, h = height.

So, let's say two sides are 3 yd and 7 yd, and height is 3 yd, so the area becomes,

(3+7)*3/2

= 10*3/2

= 30/2

= 15 yd²
