Answer:

Step-by-step explanation:

When finding a triangle's missing angle, you first have to know that all of the angles add up to 180. Then, you add the other sides, and subtract that from 180 to get the missing angle. But in this case... Your missing two... but given one other angle. So, because a straight lines angle is 180, you would take 143 and subtract it from 180 to get the other side. There is also more steps... and sorry for not explaining further... but it would take a pretty long time...

180-143=37

A=37

37+61+_=180

37+61=98

180-98=82

The missing angle is 82 degrees

-x+26=2x-10
+x +10 +x +10
36+3x
divde by 3
12=x

m∠D=2(12)-10
=24-10
=14

Which is the simplified form of the expression ((2 Superscript negative 2 Baseline) (3 Superscript 4 Baseline)) Superscript nega

AlekseyPX

Answer:

The option "StartFraction 1 Over 3 Superscript 8" is correct

That is $\frac{1}{3^8}$ is correct answer

Therefore $[(2^{-2})(3^4)]^{-3}\times [(2^{-3})(3^2)]^2=\frac{1}{3^8}$

Step-by-step explanation:

Given expression is ((2 Superscript negative 2 Baseline) (3 Superscript 4 Baseline)) Superscript negative 3 Baseline times ((2 Superscript negative 3 Baseline) (3 squared)) squared

The given expression can be written as

$[(2^{-2})(3^4)]^{-3}\times [(2^{-3})(3^2)]^2$
