What is the value of x, and what is the missing angle? NO LINKS, THEY WILL BE REMOVED

Mathematics
1 answer:
MrRissso [65]3 years ago

Answer:

x = 14

Missing angles: 33° and 57°

Step-by-step explanation:

(2x + 5) + (3x + 15) = 90° (complementary angles)

Add like terms

5x + 20 = 90

5x = 90 - 20

5x = 70

x = 70/5

x = 14

✔️Plug in the value of x to find each missing angle:

2x + 5 = 2(14) + 5 = 33°

3x + 15 = 3(14) + 15 = 57°

Hello from MrBillDoesMath!

Answer:

y = x/15


Discussion:

Given:

2x/5y = 6  =>          (multiply both sides by 5y)

(2x/5y) 5y = 6 * (5y) =>

2x = 30y =>            (divide both sides by 30)

(2/30)x = y =>

y = x/15


( or you could also multiply both sides of the original equation by "y" and then divide both sides by 6)

Thank you,

MrB

Mashcka [7]

we can see that

semicircle is cut off from a rectangle

Area of rectangle:

length =8

width =14

area =length*width

Area=14*8

Area=112

Area of semicircle:

diameter=8

so, radius =4

Area=\frac{1}{2} \pi r^2

Area=\frac{1}{2} \pi (4)^2

Area=25.13274

now, we can find resultant area

=112-25.13274

=86.86726

so, option-C..........Answer

The two inequalities that represents the constraints for the art studio classes per week are:

x + 1.5y = 40

35(x + y)  > 1,000

<h3>What two inequalities represent the constraints?</h3>

Here are inequalities signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

= means equal to

The inequality that represents the total hoursthe art studio is open would be an equal to sign. This is because the store is open for a maximum of 40 hours.

The inequality that represents the total earnings would be represented with a greater than sign because the studio earns more than $1000 weekly.
