Answer: angle EFB = 35 degrees
========================================================
Explanation:
To get angle EFC, we will average the two arc measures given
This means we add them up and divide by 2
angle EFC = (arcEC + arcBD)/2
angle EFC = (164+126)/2
angle EFC = 290/2
angle EFC = 145
Then we can say:
(angle EFB)+(angle EFC) = 180 ... the two angles are supplementary
(angle EFB) + (145) = 180
angle EFB = 180-145
angle EFB = 35
Answer:
Step-by-step explanation:
Select all of the object sets that could be modelled by perpendicular lines.
A perpendicular line is one that divides a 180 degrees line (or a straight line) into two; creating 90 degrees on one hand and 90 degrees on the other.
OPTIONS:
(A) APPLICABLE
Two roads that meet at an intersection can be modelled by perpendicular lines. Use the definition above as a yardstick.
(B) APPLICABLE
The top of the desk to the floor will represent the dividing line while the floor itself will be the 180° line.
(C) NOT APPLICABLE
A tree and its shadow on the ground will only form a right-angled triangle
(D) NOT APPLICABLE
Two stars seen in the sky cannot be modelled by perpendicular lines. They can only be modelled by a straight line; a line which extends from the first star to the other.
Answer:
1) 85
2) 150
Step-by-step explanation:
The measure of a minor arc is EQUAL to the central angle
"The measure of a minor arc is equal to the measure of the central angle that intercepts the arc. We can also say that the measure of a minor arc is equal to the measure of the central angle that is subtended by the arc."
Answer:6
Step-by-step explanation:
1.add all the numbers up 48+75+80+61=264
2. The amount of the numbers all together by how much numbers there are and there is 4 numbers so do 264/4 which is 66
The answer is 4 because there was 4 friends and the squared sandwich can be cut in half of another half
