A triangle has two angle measures of 20 degrees and 30 degrees. Find the third angle. This triangle is a(n) triangle Question 2 options:

A. acute

B. obtuse

C. right

D. it does not make a triangle

Obtuse

Step-by-step explanation:

x = missing angle

20+30+x=180

50+x=180

x=130

90<130

Thus, the triangle is obtuse

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
