Answer:
3) 74°
4) 260°
Step-by-step explanation:
3) Angle CAE is vertical to angle FAB, which is shown as 121°. Vertical angles are congruent. So, we have ...
∠DAE +∠DAC = ∠EAC
∠DAE + 47° = 121° . . . . . . . fill in known values
∠DAE = 121° -47° . . . . . . . . subtract 47°
∠DAE = 74°

4) arc MJL is the long arc that completes the circle along with short arc MJ. Short arc MJ has the same measure as its central angle, 100°. Then long arc MJL is 360° -100° = 260°.
arc MJL = 260°
This question is just giving you a fancy way of finding the surface area.
Surface area is 2(L)(w) +2(L)(h)+2(h)(w)
Plug into the equation
2(6)(8)+2(6)(18)+2(18)(8)
=96+216+288
=600
90/12=7.5.
so.....
7.5 times 15 is 21.
That added to the orginal amount equals to : 111.
How much the athletic director will pay to buy 15 more sun visors is $111.

<span>Let the smaller angle be x
The larger angle will be 3x+8
X+3x+8=180
4x=180-8=172
X=172/4
X=43
3*43+8= 137</span>

divide the term but he previous and figure out the sequence
