What 2 numbers multiply to get 40 and add to get -14
-10 and -4
(x-4)(x-10)=0
set to zero
x-4=0
x=4
x-10=0
x=10
x=4 and 10
Answer:
measure of angle A is 80 degree.
Step-by-step explanation:
isosceles triangle will have same base angles
first base angle is 50, and the second will also be 50
3 angles of a triangle will add up to be 180 degree.
A is the vertex angle.
So 50 + 50 + A = 180
100 + A = 180
A = 80.
Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35
Answer:
8
Step-by-step explanation:
The length of the diagonal line is 191 meters.
135² + 135² = c²
18225+18225 =c²
√36450 = √c²
190.91 = c
Round to the nearest meter = 191 meters
