Answer:
140
Step-by-step explanation:
SA=lw+lh+hw
6*10=60
10*5=50
5*6=30
60+50+30=140
A right angled triangle can be formed from the given scenario as shown below in the figure:
We have a perpendicular(opposite side), the measure of angle and we are interested in finding the hypotenuse.
sine of the angle relates its perpendicular side to hypotenuse as:
sin(x) = perpendicular/hypotenuse
⇒
Hypotenuse = Perpendicular/sin(x) = 13/sin(70) = 13.8 feet
This means, the length of the ladder is 13.8 feet, rounded to nearest tenth.
1/4+1/8= 0.375 in decimals but in a fraction form is 3/8 hope it helps!
Answer:
3. x= 20.1
4. x = 22.0
Step-by-step explanation:
SohCahToa. S= sin, C= cos, T=tan.
o = Opposite (the side on the other side of the given angle, also referred to as theta.)
h = Hypotenuse (the side on the other side of the right angle, represented as the square thing.)
a = Adjacent (side next to the given angle.)
3. We have opposite = x, adjacent = 24. We can use tan (Toa.)
tan(40º) = x/24 Multiply both sides times 24.
x = 24*tan(40º) Put into calculator
x = 20.1
4. We have adjacent = 12, hypotenuse = x. We can use cos (Cah.)
cos(57º) = 12/x Multiply both sides by x
x*cos(57º) = 12 Divide by cos(57º)
x = 12/cos(57º) Put into calculator
x = 22.0
Step-by-step explanation:
99+111+arc QR=360°
arc QR=360-210 =150°
again,
RPQ=150/2{inscribed angle is half of it's arc}
