Answer:
a: 55°
Step-by-step explanation:
The measure of arc NM is the same as the measure of the central angle that intercepts it: Q. The sum of the central angles of a circle is 360°, so ...
Q = 360° -120° -60° -65° -60° = 55°
The measure of arc NM is 55°.
Answer:
There are two types of similar triangle problems; these are problems that require you to prove whether a given set of triangles are similar and those that require you to calculate the missing angles and side lengths of similar triangles. Subtract both sides by 130°. Hence; By Angle-Angle (AA) rule, ΔPQR~ΔXYZ.
Step-by-step explanation:
1) given 6x = 4x + 140
2) subtract 4x from both sides => 6x - 4x = 4x - 4x + 140
=> 2x = 140
3) divide both members by 2 => 2x / 2 = 140 / 2
=> x = 70
4) Answer: x = 70
x = number of players on a team
Let's say we're talking about basketball. If each player makes a three-pointer (exactly one per player), then those players will earn 3x points overall. Now let's say the team already has 5 points to start with.
This would mean 3x+5 represents the current number of points.
