A triangle has one angle that measures 20° and another that measures 50°. What kind of triangle is it?

obtuse triange

Step-by-step explanation:

20+50=70 degrees

since a triangle adds up to 180 degrees, subtract 70 from 180 to find the measure of the final angle

180-70=110

110 degrees is obtuse since it's greater than 90, so the triangle is obtuse

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
