Answer:
x = 6
Step-by-step explanation:
The sum of angles in a triangle is 180°.
72 +64 +(4x +20) = 180
4x = 24 . . . . . subtract 156
x = 6 . . . . . . . divide by 4
Assuming angle F is 68°, angle H will be
.. 360° -2*102° -68° = 88° . . . . . . . . selection B
For example,
write 3 5/4 in simplest form.
3*4+5=12+5=17
17/4 is in simplest form.
A rectangular prism is a figure with congruent polygon bases, connected with lateral faces that are rectangles, so your answer would be rectangular prism! <span />
First we have to find the area of the trapezoid.
Let's separate the trapezoid into 3 shapes. Two triangles, and 1 rectangle.(I included an image of an isosceles trapezoid for reference)
First let's find the area of the triangles. We'll use this equation.a = areab = baseh = heighta = b · h · 0.5a = b · 3 · 0.5
We need to find the base of the triangle. To do this, we'll subtract 6 from 10, which equals 4. 4/2= 2 which is the base of the left and right triangle. Let me know if you're confused by that!!
a = 2 · 3 · 0.5a = 6 · 0.5a = 3The area of both triangles is 3.
Now we need to find the area of the rectangle. We'll use this equation.a = b · ha = 6 · 3a = 18
So the rectangle's area is 18, and both triangle's area is 3.18 + 3 + 3 = 24
Now we need to find the cost. 24 · 4 = 96
The answer is $96.
Hope this helps! :)
