Because Jill is standing directly under the kite the angle between jack Jill and the kite is 90°
so
a=12 yards
A°=61°
B°=90°
b=?
to find b we have a formula:
a devided by the sinus of A equals b devided by the sinus of B
12÷sin(61°)=b÷sin(90°)
12÷0.8=b÷1
15=b
Answer:
4 sides and all the same size!
Answer:
Step-by-step explanation:
I'm not sure if the right side is or , so I'll provide an answer for both:
Given:$75
25 hours
Painting USA : Fixed cost: $75 ; Variable Cost: $25x
Total Cost = 75 + 25(25) = 75 + 625 = 700
Upscale Home Painting: No Fixed Cost ; Variable Cost : $40x
Total Cost = 40(25) = 1,000
The most cost effective company will be Painting USA whose charge will amount to $700.
Answer:
y = 26
Step-by-step explanation:
The angles of a linear pair total 180°.
__
(2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°
7y -2 = 180 . . . . . . divide by °, collect terms
7y = 182 . . . . . . . . add 2
y = 26 . . . . . . . . . divide by 7
_____
<em>Additional comment</em>
The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.
