Answer:
2 sin x + √3 = 0
2sinx=-√3
sinx=-√3/2
x=sin-¹(-√3/2)(sin-¹ means inverse of sin)
x=-60
Answer:
Step-by-step explanation:
(5y +14)=(8y-13)
3y=27
y=9
(8y-13) +3x+ 2x+1=180
y=9, so 59 +4x+1=180
120= 4x
x=4
angle RSP = 9
Answer:
106355.844
Step-by-step explanation:
45.8*34.2=1566.36
1566.36*67.9=106355.844
Answer : 1x,-3y /2x,-5y — every time the x change it adds 2 to the y
There is a square and a half circle.
To find the radius of the circle: 18in - 12in = 6in
Area of a circle = (pi)r^2 = 3.14 (6in)^2 = 3.14 (36in^2) = 113.04in^2
This is an half circle, so we have to divide by 2 the result
56.52in^2 in what we’re looking for.
Area of the square = (12in)^2 = 144in^2
Total area = (144 + 56.52)in^2 = 200.52in^2
Or 201in^2 to the nearest whole number.
