Answer:
1) 8.9 cm
2) 44.5 cm^2
Step-by-step explanation:
a) we want to calculate the length of the arc
Mathematically, we use the formula for the length of an arc
That will be ;
theta/360 * 2 * pi * r
theta = central angle = 51
r is radius = 10 cm
so we have ;
51/360 * 2 * 22/7 * 10 = 8.9 cm
2) The area of the sector is;
theta/360 * pi * r^2
51/360 * 22/7 * 10^2
= 44.5 cm^2
Answer:
d
Step-by-step explanation:
155$ after 3 months means 45$ less. 45$ divided by 3 (the number of months) =15
that means she spends 15$ per month
Answer:
To calculate the simple interest, we say
S.I = (PxRxT)/100
Where P = the principal amount
R= rate in terms of %
And T= time.
Now P= $100 000
R= 8%
T= 3 years
S.I= (100,000 x8 x3)/100
=$2 400 000/100
= $24, 000
So the interest is 24000
Total amount he will be having = 100000 + 24 000
The total money he will be having in 3 years time = $124 000

Answer:
BC=YZ
Step-by-step explanation:
The SAS Congruency states that if two sides and one angle in a triangle are equal then the triangles are said to be congruent.
It is given that,
angle B= angle Y
AB=XY
to prove they are congruent we need to show that BC=YZ
HOPE IT HELPS :)
PLEASE MARK IT THE BRAINLIEST!
I’m pretty sure the answer would be “C” I’m not sure though
