20 POINTS I NEED HELP WITH THIS PLZZ HELP ME!!

Mathematics
1 answer:
rusak2 [61]3 years ago
8 0

Answer:

I think A

Step-by-step explanation:

Because if you change it from (43 + 60) + 40 to (60 + 40) + 43 = 143

You automatically know it is 143 because 60 + 40 is 100 + 43 = 143

And it wouldn't be D because that is already in a easy way the solve. The others looked to complicated to even attempt so it has to be A.

Did this help!!??

Triangle QRS has the angle measures shown.
galina1969 [7]

Answer:

108 degrees

Step-by-step explanation:

Given the following angle measures in triangle QRS

m<Q = 1x

m<R = 3x

m<S = 6x

Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees

The sum of angle in a triangle is 180 degrees

m<Q + m<R + m<S = 180

1x + 3x + 6x = 180

10x = 180

x = 180/10

x = 18

The obtuse angle is 6x

Measure of the obtuse angle = 6x

Measure of the obtuse angle = 6(18)

Measure of the obtuse angle = 108 degrees

Hence the measure of the obtuse angle is 108 degrees
