The value of y is 26.

<u>Step-by-step explanation:</u>

When 2 angles are called as linear and adjacent formed by crossover of two lines, then the measurement of straight angle is equal to 180 degrees.

A pair of linear angles added to produce 180 degrees.

m ∠ACD + m ∠DCB = 180°

(5y+3)° + (2y-5)° = 180°

Grouping the terms on the same side as,

5y+ 2y + 3°-5°= 180°

5y + 2y = 180°- 3°+5°

  7y = 182°

Dividing by 7 on both sides, we will get,

y = \frac{182}{7} = 26

So the value of y is 26.

The diagonals of a rhombus are 21 m and 32 m. What is the area of the rhombus?<br> 30 POINTS
Wittaler [7]
I have included attachment below

so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2

answer is 336 m^2

Roger's Cafe has usual daily earnings of $800. Today, the cafe earned 120% of the usual daily earnings. How much did they earn t
riadik2000 [5.3K]

Answer:

960

Step-by-step explanation:

Over here, I'm going to do it in two ways, and either way works, one is just easier to do out:

1st way:

You can represent the percent 120 as a decimal which is 1.20, then you do 800*1.2.

2nd way:

You can use benchmark percents. You find 10 percent of 800 which is 80 and multiply 80 by 2 to get 160, so 20% is 160 dollars. Then you add 160 to 800 (800+160) and get 960.

Please tell me if you have any questions.
