Answer:
--------------------------------------------------
Step-by-step explanation:
60+x-45+x=180
60-45+2x=180
15+2x=180
2x=180-15
2x=165
x=165/2
x=82.5
Answer:
∠x = 67°
Step-by-step explanation:
∠x = 67° because they both are inscribed angles of the same arc
Answer:
formula: y-y1 = m(x-x1)
Step-by-step explanation:
General:
1. find 2 points directly on the line and apply the formula y2-y1 over x2-x1 this answer equals m
2. then add it into the formula y-y1 = m(x-x1) remember x and y are variables so only put numbers in y1 and x1
3. solve the problem
Example:
line 1:
1. y2-y1 over x2-x1 is 4-6 over 6-4 = -1
2. y-6 = -1(x-(-4) or y-6 = -1(x+4)
3. y-6 = -1x-4
4. y = -1x-2
3. the gradient equals: y = -1x-2
Hope this helps :) Let me know if you need a better example
Answer:
Longer side is 75 feet, shorter side is 50 feet.
Step-by-step explanation:
Let l be the length of the longer side and w be the length of the shorter side.
2l + 2w = 250, which simplifies to
l + w = 125. Solving for w, we have
w = 125 - l.
lw = l(125-l) = 3750
l = 75, w = 50
The answer would be D. because the point-slope formula is y-y1=m(x-x1). Since both of the numbers in the point are positive the equation will be the same. You will just substitute the numbers into the equation making it answer D.
