Answer:
B = C = 70°
Step-by-step explanation:
In Triangle ABC, angle A measures 40 degrees.
We need to find the possible angle measures for B and C if ABC is in isosceles triangle.
For an isosceles triangle, two sides of a triangle are equal. We know that if two sides are equal, the corresponding angles are equal. Let equal angles are x. The sum of an isosceles triangle is equal to 180 degrees. So,
40 + x +x = 180
40 + 2 x = 180
2x = 140
x = 70 degrees
So, the possible angle measures for B and C is equal to 70°.
The probability that the spinner land on 5 in two successive spins is 1/100.
Step-by-step explanation:
Total numbers on the spinner = 10
Probability that the spinner land on 5 for the 1st time = 1/10
Probability that the spinner land on 5 in two successive spins = (1/10) x (1/10)
= 1/100
The probability that the spinner land on 5 in two successive spins is 1/100.

2/3 * 4/4
Answer:
Approximately 12.04 units.
Step-by-step explanation:
The find the distance between any two points, we can use the distance formula, which is:
We have the points (2,7) and (-6,-2). Let's let (2,7) be (x₁, y₁) and let's let (-6, -2) be (x₂, y₂). Substitute:
Subtract:
Square:
Add:
Approximate
So, the distance between (2,7) and (-6,-2) is approximately 12.04 units.
And we're done!
