Answer:
n+7
Step-by-step explanation:
When we have any unknown quantity, we can call it mostly x,y,z
so, here
Let take an unknown number = n
then
we need to do here " sum of a number and 7 in algebraic form"
so, it becomes
n + 7 (Answer)
Answer:
Supplementary angles are two angles whose measures add up to 180 degrees. ... Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are ... If the measure of the angle is twice the measure of the other, find the measure of each angle.
Step-by-step explanation:
Answer:
graph C
Step-by-step explanation:
because the vertex is h,k. h is -3 k is -25. C is the only graph with a vertex at that location.
Answer:2
Step-by-step explanation:
(2x+5)/3 = 3/2
Multiply both sides by 3:
2x + 5 = 9/2
Subtract 5 from both sides:
2x = 9/2 - 5 = 9/2 - 10/2 = 3/2
Divide both sides by :
x = 3/4
Answer:
96
Step-by-step explanation:
IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."
Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π.
π = C
D .
Since D = 2r, then
π = C
2r
or,
C
r = 2π .
arc lengthThat ratio -- 2π -- of the circumference of a circle to the radius, is called the radian measure of 1 revolution, which are four right angles at the center. The circumference subtends those four right angles.
arc length
Radian measure of θ = s
r
Thus the radian measure is based on ratios -- numbers -- that are actually found in the circle. The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For, the ratio of s to r does determine a unique central angle θ.
