X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.
So your answer is
x=72
Acute Triangle
Step-by-step explanation:
Let the width=x
Length =6x-4
As we know that in a rectangle




- Here a=6, b=-4, c=-20.
- use quadratic formula

193.80
Step-by-step explanation:
30x6.46=193.80
Answer:
Step-by-step explanation:
Easy the three angles of a triangle equal 180 degrees
so 60+75 = 135 --> 180-135=
1) 145
2) 35
3) no since the tops a 100 and its a Isosceles triangle two corners left it be 40 for each corner
4) 34 for both x's cause 34+34+112. = 180
5) 180- 120= 60- 10 = 50/4 is (12.5)= x
6) x = 15 cause it be 120- 60 to get 60
