Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
Answer:
21°
Step-by-step explanation:
We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.
5x+6=16x-27
Continue to solve . . .
33 = 11x
x=3
Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get
(16 x 3) - 27, which is equal to 21°.
Answer:
Step-by-step explanation:
2x2=4 divided by 2 =2
2x2=4
2x4=8
2+4+8=14
In the given question, it is given that ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.
And we have to find the value of tan B.
And tangent of any angle is equal to the ratio of vertical by horizontal. That is:
tanB=8/15
And that's the required missing ratio for tan B.
Answer:
2 12/15 and 2 10/15
Step-by-step explanation:
4 x 3 = 12
2 x 5 = 10
