Find the measure of y. Polygon Angle-Sum theorems

Alchen [17]

Answer:

z = 70°

y = 103°

Step-by-step explanation:

From the picture attached,

110° + z° = 180° [Supplementary angles]

z = 180 - 110

z = 70°

Since sum of interior angles of a polygon = (n - 2)×180°

where n = number of sides of the polygon

For a quadrilateral (n = 4),

Sum of interior angles = (4 - 2) × 180°

= 360°

z° + y° + 100° + 87° = 360°

70° + y° + 187° = 360°

y = 103°

Therefore, measure of the angles x = 70° and y = 103°.

a shipment of sugar fills 4 1/3 containers. if each container holds 2 1/7 tons of sugar, what is the amount of sugar in the enti

emmasim [6.3K]

To find the answer we need multiply the number of containers by number tons of sugar each container has.

(4 1/3 )*(2 1/7).

To calculate , we need to convert mixed numbers into improper fractions.

4 1/3 = (4*3 +1)/3 = 13/3

2 1/7 = (2*7+1)/7 =15/7

(4 1/3 )*(2 1/7) = (13/3) * (15/7) = (13*5)/7 = 65/7 = 9 2/7 (tons)

Answer: 9 2/7 tons.

On Friday night, Alex ate a large pizza for dinner and had LaTeX: \frac{3}{5}3 5 of the pizza left over when he was done. On Sat

ludmilkaskok [199]

Answer:

Alex ate $\frac{3}{10}$ of the large pizza on Saturday.

Step-by-step explanation:

Given:

Amount of Pizza which was left over on Friday = $\frac{3}{5}$

Amount of Pizza ate on Saturday = $\frac{1}{2}$ of the Amount of Pizza was left over on Friday

We need to find how much did Alex eat on Saturday.

Solution;

Since we know that Alex ate on Saturday $\frac{1}{2}$ of the Amount of Pizza which was left over on Friday.

So to find the amount he ate n Saturday we will Multiply $\frac{1}{2}$ with the Amount of Pizza which was left over on Friday.

framing in equation form we get;

Alex ate on Saturday = $\frac{1}{2}\times \frac{3}{5}= \frac{3}{10}$

Hence Alex ate $\frac{3}{10}$ of the large pizza on Saturday.
