Hey,
We can see here 2 of the angles are equal and the third one is a right angle right?
That means it is an isosceles triangle since they have 2 equel angles and a right anlgle.
Another feature of the isosceles triangle is that 2 sides are equal.
We are given one side is 5.5 right?
So the side BC has to be 5.5 or the side AB has to be 5.5
In isosceles triangles the side opposite to the 90 degree angle is the hypotenuse.This means it is the longest angle.
So it has to be AB which is equal to 5.5 since BC is the hypotenuse.
Hope this helps,Happy New Year
Answer:
79 units²
Step-by-step explanation:
The area of a circle is found by using the formula A = π x r². Since we are not given the radius we can use the formula r = C / (2π). Substituting in the given values, we get r = 31.5/(2π). 2 times pi is 6.283185307. 31.5 divided by this will get you 5.013380707. Now, put that value in for r in the area equation. A = π x 5.013380707². Pi times 5.013380707² equals 78.96074613. This can be rounded to 79. (Or 80 if you need to the nearest whole number.)
1/2 is less than 1
4/3 is more than 1
It should be c really hope this helps and im right have a blessed day:)
Let's solve the equation step-by-step
Step 1) Simplify both sides of the equation
3+ j/11 = 2
1/11j+3=2
Step 2) Subtract 3 from both sides
1/11j + 3 - 3 = 2 - 3
1/11j = -1
Step 3) Multiply both sides by 11
11 x (1/11j) = (11) x (-1)
j = -11
Answer is.. J = -11
