9) Here, Two angles are unknown without any relation not even a variable.
So, we could calculate the sum of that two unknown angles only,not their individual magnitude.

It would be: 50 + 152 + missing angles = 360
m.a = 360 - 202
m.a = 158

In short, Sum of two Unknown angles would be 158

10) Here, ABCD is a Quadrilateral, so their adjacent side would make a linear pair equation, means their sum would be equal to 180

So, ∠1 + ∠2 = 180

Hope this helps!

For 9: All the angle should add up  to 360 degrees.

So 152+50=202

360-202=158 degrees (Missing angle measure)

Method being used: All angle should add up to 360 degrees.

David will spend at most $39 on gifts. So far, he has spent $22. What are the possible additional amounts he will spend? Use c f
iren2701 [21]

Answer:

c\leq \$17

Step-by-step explanation:

Let

c -----> the additional amount (in dollars) David will spend

we know that

The word " at most" in this context means "less than or equal to"

The amount David has spent plus possible additional amounts he will spend must be less than or equal to $39

so

The inequality that represent this situation is

22+c\leq 39

solve for c

subtract 22 both sides

c\leq 39-22

c\leq \$17

The maximum amount he could spend is $17

PLEASE HELP!!!!!!!

The correct answer is: <span>C) The base of the cone and the top of the cylinder have the same area. </span>The cone has the smallest volume of the 2 figures. This is because the formula for the cylinder is b x h, the formula for the cone is 1/3(b x h) so if they have same height and base area cylinder would have larger volume because, for the cylinder, a formula is one-third of b x h. Hope I helped!!  : )

hope this helps you

5,000 tens equals how many thousands
Brilliant_brown [7]

5,000 tens = (5,000 x 10)

To find out how many thousands are in it,
just divide:

(5,000 x 10) / (1,000)  =  (5 x 10)  =  50 of them .
