Answer:
A is the answer
Step-by-step explanation:
Becuase if it has the same radius and the same height. then they will both be equal.
Answer:
m∠A = 90°
Step-by-step explanation:
In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!
m∠B = m∠C
11x - 10 = 7x + 10
4x - 10 = 10
4x = 20
x = 5
Now let's insert x back in the expressions for angles.
m∠B = (11x − 10)° = (11(5) − 10)° = 45°
m∠C = (7x + 10)° = (7(5) + 10)° = 45°
<u>Sum of all angles in the triangle is 180°.</u> Let's make an equation.
m∠A + m∠B + m∠C = 180°
m∠A + 45°+ 45° = 180°
m∠A = 90°

On the number line, move 4 units to the right. End at -2. The dolphin was 2 feet below sea level.
<h3>What is number line?</h3>
A number lines are the horizontal straight lines in which the integers are placed in equal intervals.
A dolphin was swimming 6 feet below sea level. It then swam up 4 feet.
So, -6+4= -2 feet
As, from the information
On the number line, move 4 units to the right. End at -2. The dolphin was 2 feet below sea level.
This is because the dolphin 6 feet below sea level and swam up 4 feet.
