Answer:
145
Step-by-step explanation:
Angle 4 and 5 are the same.
Which means that angle 3 and 6 are the same.
A straight line has an angle of 180 degrees in total.
This means that we have to subtract 35 from 180.
This gives us 145.
So, the missing angle is going to be 145 degrees.
*also, 1, 4, 5, and 8 are the same angle.
**2, 3, 6, 7 are also the same angle.
***I just remember learning about this last year, don't remember what there called tho.
Answer:
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3·B·h
where B represents the area of the base and h represents the height.
The area of a triangle is given by the formula ...
A = 1/2·b·h
where b represents the length of the base of the triangle, and h represents the height of the triangle.
For a right triangle, the base and height can be taken to be the lengths of the two legs. Then we have
A = 1/2·(15 cm)·(24 cm) = 180 cm²
The volume of the pyramid is then ...
V = 1/3·(180 cm²)(13 cm) = 780 cm³
The volume of the pyramid is 780 cm³.
Answer:
x = 24
Step-by-step explanation:
Since this is a right angle, we can use the Pythagorean Theorem to find x. In the formula, a^2 + b^2 = c^2, variables a and b represent the lengths of the legs, and variable c represents the length of the hypotenuse.
a^2 + b^2 = c^2
18^2 + x^2 = 30^2
324 + x^2 = 900
x^2 = 576
x = 24
