Answer:
Step-by-step explanation:
Part A:
3x+12+7x+88=180
10x+100=180
10×=80
X=8
Part B:
m<RPS=3x+12
(3*8)+12
=36
Both the angles will be 105°
Just add up the given angles, subtract the result by 360, and divide by 2.
Answer:
d. 1.5, 1.25, 0, -0.5, -5
Step-by-step explanation:
1.5 > 1.25 > 0 > -0.5 > -5
Well it is obvious that 1.5vis greater than 1.25.
0 is greater than any negative integers, and that the higher negative number it's value is lower. For example:
-10,000 is less than -100
-4 is greater than -10
9514 1404 393
Answer:
100°
Step-by-step explanation:
The relevant relation for angle x is ...
x = (AB +DE)/2
and for angle y, it is ...
y =(AC -DE)/2
Using the second relation to write an expression for DE, we have ...
DE = AC -2y
In the first equation, this lets us write ...
x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2
2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2
(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3
AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values
AC = 100°
