Answer:
Step-by-step explanation:
The area of a circle is pi multiplied by the radius squared: .
The figure shows a diamater equal to 14 m, so the radius is half of that, 7 m.
A calculator gives a decimal approximation of 153.94 meters squared. (
3.5g+12.2 is the simplified expression I believe
Answer:
Step-by-step explanation:
What is known....AC=75 AB=4 times BC AB+BC=AC
4(BC)+BC=75 Add like numbers
4(BC)+BC=5BC
5(BC)=75 get the variable(BC) alone by dividing both sides by the number(5)
5(BC)/5=75/5 Then simplify....5(BC)/5=(BC) and 75/7=15
(BC)=15
Answer:
g (-2) = 22
Step-by-step explanation:
Evaluate g( -2) if g(x) = x^2 – 4x + 10
g(-2) = (-2)^2 - 4(-2) + 10
g(-2) = 4 + 8 + 10
g (-2) = 22
Answer with explanation:
it is given that ,in ΔABC,
∠BAD=20°, and ∠CAD=54°
We have to adjust point D,so that measure of angle BAD is equal to the measure of angle CAD.
that is, if point D is moved to right of B,then ∠BAD increases from 20° to (20+x)° and ∠CAD decreases from 54° to (54-x)°.
→20 +x=54-x
⇒ 2 x= 54 -20
⇒2 x=34
x=17°
Using angle bisector theorem, if AD bisects ∠B AC.
so,
If, ∠BAD=∠CAD=37°, then
1. AD bisects ∠B AC.→→→Option A
