You're finding the area of two shapes, a square, and a quarter of a circle.
So
A=As+Ac/4
A=Lw+πr²/4
A=(6)(6)+(3.14)(6²)/4
A=64.26 m²
4:
Line LKJ is a straight line, so <LKJ =180°
<LKJ=<JKH+<HKL
180=78+4x+2
180=80+4x
100=4x
25=x
<HKL=4x+2
<HKL=4(25)+2
<HKL=102°
This is the general formula for circle.
x² + y²=r²<span> ,where r is the radius
</span>
Consider the building as the centre of the circle, then the radius is equal to the furthest distance between <span>you and the tower that allow you to have coverage.
Hence,
r</span>² = 2025
r=√2025 = 45 miles
Answer: 17.80 is ur final answer
BRAINLIEST PLZZZZZZZZZ
Step-by-step explanation:
Well we know that all the sides are congruent so you can use SSS
There are two sides and one angle that is congruent therefore SAS
You have pairs of legs that are congruent so LL
Lastly we know that JK and QR are congruent so you get HA
Hope this helps :)
Answer:
(2,-1)
Step-by-step explanation:
We know that,
Whenever a point lies on the graph of an equation, the coordinate pair of the point will be a solution to the equation.
As in this case,
(2,-1) lies on the lines of both Equation 1 and Equation 2. Hence, their common solution is (2,-1).
