Answer:
C
Step-by-step explanation:
The triangle is an equilateral triangle, which is equal on all three sides in both side length and angle. since one of them of 60 degrees, then all of them would also be 60 degrees. Since the total amount of degrees in a triangle is 180, 60*3=180 so the answer is C.
Answer:
Step-by-step explanation:
4)
Given the expression
a+b-c
substituting the values in the expression
a+b-c = 4.1+5.7-0.3
= 9.8 - 0.3
= 9.5
5)
Given the expression
10-(a+b)
substituting the values in the expression
10-(a+b) = 10 - (4.1+5.7)
= 10 - 9.8
= 0.2
6)
Given the expression
b-c+2
substituting the values in the expression
b-c+2 = 5.7 - 0.3 +2
= 5.4 + 2
= 7.4
Answer:
132, 390, 244, 492
Step-by-step explanation:
those are the answers in order
The legs of an isosceles triangle are congruent; they have the same length, so if one leg measures 2 m, the other leg also measures 2 m.
2m + 2m + b = 7.5 m
b + 4 m = 7.5 m
b = 3.5 m
The length of the base is 3.5 m.
