Ricardo will be cool is how and he is smart
Answer:
I believe these are the answers.
Step-by-step explanation:
Find each of the angle measures:
<1=65 degrees
<2=115 degrees
<3=60 degrees
<4=60 degrees
Answer:
12^2 + 15^2 = 18^2
Step-by-step explanation:
If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle
a^2 + b^2 = c^2
12^2 + 15^2 = 18^2
If this is true, then the triangle is a right triangle
Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7
Triangles equal 180 degrees total
It’s a right triangle so one of the angles is 90 degrees and we know another angle is 36.6
So 90+36.6= 126.6
180-126.6= 53.4
So I’m assuming the correct answer is C since that’s the closet number to 53.4
