what do you need to know? you should write the question
Answer:
8
Step-by-step explanation:
12 +4x = 36
Then solve the linear eqn
Answer:
Hence the required dimension is 4cm.
Step-by-step explanation:
Given:
An Isosceles triangle with uneven side=l+1 cm
Area= 6 sq cm
To Find:
Height of Triangle.
Solution:
We know that area of triangle given by,
Area=1/2*base*height.
Here height =1+base
6=1/2((b+1)*b
12=(b+1)*b.
b^2+b-12=0
(b-3)(b+4)=0
b=3 or b=-4
So length never be negative
so b=3 cm
And height=b+1=3+1=4 cm.
You have to make them have the same denominator so
1/2=2/4
Then you add them together
2/4+3/4=5/4
You have to make it a mixed fraction.
4 goes into 5 one time and has a remainder of 1 so you get 1 and 1/4?
Answer:
Step-by-step explanation:
Given that,
The radius of circle, r = 7 cm
The area of sector, A = 44cm²
We need to find the angle of the sector. The formula for the area of sector is given by :
Solve for 
.
So, the angle of the sector is equal to 
.
