Answer:
angle 1: 44 degrees
Angle 2: 44 degrees
Angle 3: 68 degrees
Step-by-step explanation:
since these triangles are isosceles the 2 bottom angles are equivalent
Also sup um of all three angles of a triangle equal 180 degrees
We know 2 angles of the triangle to the left and they are both 68 degrees so to find angle 1 we multiply 68 by 2 first
68x2
136
Now subtract 180 from that
180-136
44 degrees is angle 1
Angle 2 is equal to angle 1 since it’s across like that
So angle 2 is 44 degrees
And since they both are isosceles we know angle 3mis 68 degrees also since the 2 bottom angles have to be the same

Answer:
15 students
Step-by-step explanation:
First, change the fraction to a decimal: 6/10 = 0.6
Next, multiply 25 with 0.6: 25 x 0.6 = 15

Answer: sides
Step-by-step explanation:
The orthocenter of the triangle will be the intersection of the three altitudes of a triangle. The orthocenter has several vital properties with other parts of a triangle, including the area ,incenter circumcenter and more. Typically, the orthocenter is represented by letter H.
The altitude of a triangle is a line that passes through the vertex of a triangle and it is also perpendicular to the opposite side. The orthocenter of a triangle can lie outside the triangle because an altitude may not necessarily intersect the side.
Answer:
Step-by-step explanation:
see the attached figure , to better understand the problem
we have
where
A(b) ---> is the trapezoid's area
b ---> is the other base value
Solve the equation for b
That means ----> isolate the variable b
Divide 12 by 2 right side
Divide by 6 both sides
subtract 9 both sides
Rewrite

Answer:
252m^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is 2(hl)+2(hw)+2(wl).
we just plug in the values.
2(12 x 6) + 2(12 x 3) + 2(6 x 3)
= 2(72) + 2(36) + 2(18) then simplify
= 144 + 72 + 36
= 252
