Answer:
(7 1/2 / 5) / 6 = 0.25
Step-by-step explanation:
-20 x 2 or -10 x 4 both equal -40
-2 x 3 = 6
Answer:
Part A: equations B and D are true
Part B: expression B is equal to tan(g)
Step-by-step explanation:
In the given triangle, sin(g) = cos(h) and cos(g) = sin(h).
___
Part A
Based on the above, selection B is true.
Based on the above, the equation of D becomes: sin(h)+sin(g) = sin(g) +sin(h), which is true.
Selections B and D are true
___
Part B
Based on the above tan(g) can also be written ...
tan(g) = cos(h)/sin(h) . . . . . corresponds to selection B
Answer: D. They are both congruent
Step-by-step explanation:
The only difference in the two shapes is the locations. One shape is located in the 4th (-x, +y) quadrant, while the other shape is located in the 2nd quadrant (+x, -y)
They two shapes are the same size with the same area, so they are both congruent.
Answer:
83
Step-by-step explanation:
The sum of the angles of a triangle is 180
x + 2x+1 + x+ 15 = 180
Combine like terms
4x+16 = 180
Subtract 16 from each side
4x+16-16 = 180-16
4x = 164
Divide by 4
4x/4 = 164/4
x = 41
The angles are
x=41
x+15 = 41+15 = 56
2x+1 = 2*41+1 = 82+1 = 83
The largest angle is 83
