Answer:

Step-by-step explanation:

Both parallel sides are called bases. To find the area of a trapezoid we need to divide it into two triangles. Both triangles produced have the height h. The area of the trapezoid is the sum of the areas of the two triangles.

Measure the angle of 10x+10

Elena L [17]

Answer:

We know that opposite angle are congruent.

$10x + 10 = 11x + 3 \\ \\ 10x - 11x = - 7 \\ - x = - 7 \\ x = 7$

So, We found out that x = 7,

So, Putting x = 7 in 10x+10

$10 \times 7 + 10 \\ \\ = 70 + 10 \\ \\ = 80$

So, The measure of angle 10x+10 is 80.

A sum of Rs.750 is in the form of denominations of Rs.50 and Rs.100. If the number of 100-rupee notes is twice the number of 50-

Naddik [55]

Answer:

100 rupee notes= 6, 50 rupee notes=3

Step-by-step explanation:

3 x 50 = 150

6 x 100 = 600

600 + 150 = 750

and 3 x 2 = 6, so the amount of 100 rupee notes are twice the amount of 50 rupee notes.

Hope this helps :)

Which expression can be used to determine the length of segment ZY? See image.

mixer [17]

Answer:

$\sqrt{8^{2} + 3^{2} }$

Step-by-step explanation:

We see that this is a rectangle triangle, and that the ZY side is the hypotenuse.

It's length is then square root of the sum of the squares of the other sides:

$hyp = \sqrt{a^{2} + b^{2} }$

So, in this case:

$ZY = \sqrt{8^{2} + 3^{2} }$

The 8 and 3 numbers are easy to get from the graphic... and the order doesn't matter (8² + 3² = 3² + 8²).

That's an easy rule to remember.

I hope it helps.
