Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...
7x + 15 = 8x
Now we just solve for x
7x + 15 = 8x
15 = 8x - 7x
15 = x
We Can check to see if it is correct by substituting 15 in for x in the equation..
7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120
It checks! angles B and D = 120 degrees
22.5240 rounded to the nearest thousandth is 22.524. For this decimal
number to be rounded up rather than down, the original number would have
had to been 22.525 or higher.
To solve 47, you would add.
a² (33) + b²(44) = c²
33² = 1,089
44²= 1,936.
1,089 + 1,926= 3,024.
√3,024= 54.9
to solve 48, you would subtract.
9² - 5.4² =x²
9² = 81.
5.4²= 291,16.
81 - 29.16= 51.84.
√51.84=7.2
7.2 = x
hopefully this helps
Answer:
The answer is c
Step-by-step explanation:
you take 2 - 1 and divide by -3-0 and get -1/3 which is the slope
