Answer:
x = 16
Step-by-step explanation:
It's a 30°60°90° triangle.
The side opposite to 30° is 8.
x is the side opposite to 90°
8 * 2 = 16
Answer:
the last one [d)]
Step-by-step explanation:
First, we need to use the triangle inequality theorem. The sum of the lengths of the two sides must be greater than the third side.
a) 7+14=21=21 (this cannot represent a triangle)
b) 13+23=36<37 (this cannot represent a triangle)
c) 7+18=25=25 (this cannot represent a triangle)
d) 11+24=35>32 (this can represent a triangle)
d) is the answer
Hope this helps!
Answer:
151.5 cm^2
Step-by-step explanation:
lets cut stright acrros so you have a triangle 13 (base) by 3 cm (high)
area of a triangle is 1/2 base times hight --> 13x3/2 = 19.5cm^2
now lets doi the rectangle that is 12 by 11
Length times hight is the area is 132
add both areas 132 + 19.5
0.4 * x = 68
x = 68/0.4
x = 170
check:
0.4 * 170 = 68
