Answer: both of them made ok estimates but i think issacs was better. hope this helps! ^-^
Step-by-step explanation:
Answer:
Step-by-step explanation:
(Sin27) / 11 = (sin x) / 15
cross multiply
15 sin27 = 11 sin x
keep in calculator as you divide 15sin27 by 11.
sin x = .6190779542
do sin ^ -1 (.6190779542) (It’s a key on the calculator.)
x = 38.25*
Answer: 33y
Step-by-step explanation:
17+18=35
4 x y =4y
4 x -16 = -64
(64-35=29)
29y + 4y= 33y
Answer:
m∠CEA = 90°
∠CEF is a straight angle
∠AEF is a right angle
Step-by-step explanation:
we know that
BE bisects ∠CEA -----> given problem
so
m∠CEB=m∠BEA
m∠CEA=m∠CEB+m∠BEA
The measure of angle CEA is a right angle -----> m∠CEA=90°
The measure of angle CEF is a straight angle -----> m∠CEF=180°
m∠CEF=m∠CEA+m∠AEF
The measure of angle AEF is a right angle -----> m∠AEF=90°
therefore
The statements that must be true are
m∠CEA = 90°
∠CEF is a straight angle.
∠AEF is a right angle
Im not sure how to put the sign here but x= long division sign 3+5, negative sign in front of long division sign 3+5
