The correct answer for the question that is being presented above is this one:
(1)
The triangle shows and equilateral triangle. Equilateral triangle has the same length of sides and angles.
60 = 1.5x
x = 40 degrees
7.1 = y + 3.4
y = 3.7 cm
(2) Isosceles Triangle
65 = 13x
x = 5 degrees
y + 2/3 = 7/8
y = 7/8 - 2/3
y = 21 - 16 / 24
y = 5/24 in
(3)
12 = x + 3.8
x = 8.2mm
Answer:
x=2.5
Step-by-step explanation:
the first thing you want to do is simplify like terms.
you could say this is as 4(x+7)=38
this can easily be solved algebraically.
first use distributive property on the four
this leaves you with 4x+28=38
next, subtract 28 from both sides
4x=10
now divide everything by four and you get x=2.5
Answer:
18
Step-by-step explanation:
9+9=18 both sides of the rectangle is 9 so the top is longer which means 18
