Find the measure of angle A. 71° x+49 +72

Mathematics
1 answer:
slega [8]2 years ago
5 0

Answer: 66 degrees

Step-by-step explanation:

Sum of the angle measures is 180, so:

71 + x + 49 + x + 72 = 180

2x + 192 = 180

2x = -12

x = -6

Meaning the measure of angle A = -6 + 72 = 66 deg.

1/6d + 2/3 = 1/4(d-2)
xxMikexx [17]
D = 14

1/6d + 2/3 = 1/4d - 1/2
2d + 4*2 = 3d - 6
2d - 3d = -6-8
-d = -14
d = 14

ok so i did learn this and was really good at it but now that I have to do it I cant.....how do i find the perimiter and area...
musickatia [10]

Hi!

So what you want to do is to find the perimeter add the sides up 4 times or mutiply 3.5 and 4. It's the same thing

Perimeter: 3.5*4= 14

For area multiply 2 sides and only 2 sides which are the length and width

Area: 3.5 * 3.5 = 12.25

Hope this helps!!

Given y < 4x – 6, explain how to graph this and decide whether or not (– 1, 5) is a solution to this inequality
svp [43]

the point (-1,5 ) is NOT a solution to the inequality.

There are three steps in graphing an inequality:

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥)

or below the line for a "less than" (y< or y≤).

Now to solve this, graph the line y=4x-6

Lets use the point (0,0)

0<-6, is NOT true

So we shade everything to the left of the line y=4x-6

Hope that helped.
