In every triangle,if one of those three angles has his measure more than 90°,then the triangle is optuse.
If all three angles are 60°,it means the triangle equiangular.
If one of those three angles is equal to 90°,the triangle is right.
If all the angles of the triangle have their measure less than 90°,the triangle is acute.
_____________________________________________________________
Your triangle has an angle bigger than 90°,it means the triangle is optuse.
Answer:
Step-by-step explanation:
Slope formula
Here
Slope can be calculated as
I will help you if you show me what questions 1,2,3,4 are.
30 because the angles of the triangle should be 180. Since we know one is 90 the other is 60 so 180-(90+60)=30
3(x-7) = 138 + 3x First multiply
3x-21 = 138 + 3x subtract 3x from both sides
-21 = 138
This is a false statement because -21 does not equal to 138 so the answer is no solution.
