Answer:
A. <BED and <DEA, <AEC and <BEC
Step-by-step explanation:
Supplementary angles add up to give 180°.
m<BED = 90°
m<DEA = 90°
m<BED + m<DEA = 180°
Therefore, <BED and <DEA are supplementary.
m<AEC = 90°
m<BEC = 90°
m<AEC + m<BEC = 180°
Therefore, <AEC and <BEC are supplementary.
Answer:
4.0
Step-by-step explanation:
Given that
3.9931
Now rounded to one decimal places
3.9931 = 4.0
So the above value would be rounded to one decimal places after rounded off it comes 4.0
Answer:
x = 82°
y = 59°
z = 39°
Step-by-step explanation:
∠x = 1/2(134° + 30°) = 82°
∠z = 180° - 59° - 82° = 39°
arc DF = 2(39°) = 78°
arc DB + arc DF = 134° + 78° = 212°
draw a diameter down from point B to the opposite side of the circle, call that point P:
arc BDP = 180°
(arc BDF) 212° - 180° = 32° (arc PF)
∠PBG = 1/2(32°) = 16°
∠DEB = 1/2(134°) = 67°
∠DBE = 180° - 59° - 67° = 54°
(∠DBE) 54° - (∠z) 39° + (∠PBG) 16° = (∠PBE) 31°
y = 90°- 31° = 59°
Answer:
Angle 4 is greater, it looks like is a 90 degree angle. so I will say is angle 4
Answer:
A; scale = 1/4, length = 1, height = 3/4.
B; scale = 2.5, length = 5, height = 15.
C; scale = 3, length = 6, height = 6.
Step-by-step explanation:
for A.
if one scale which means length of one small square is 1/4. we can see that the base of A has 4 scales with a value of 1/4. so to get the length you multiply the scale which is number of scales in the base which 4 if you look at the base. 1/4 x 4 is 1. to find height you multiply the scale with the number of scales upward which you can see has 3 scale so height is 1/4 x 3 = 3/4. you apply the same method to the other two to get the answer.
