Answer:

x = 94°

Step-by-step explanation:

The measure of the chord- chord angle CED is half the sum of the arcs intercepted by the angle and its vertical angle, that is

\frac{1}{2} ( arc CD + arc AB ) = 82°

Multiply both sides by 2 to clear the fraction

CD + AB = 164°, that is

x + 70 = 164 ( subtract 70 from both sides )_

x = 94°

an 8 feet ladder leans against the side of a house. how far is the bottom of the ladder from the side of the house when the angl
Natali [406]

Answer:

Since it's a right angled triangle,

taking 61 as reference angle,

cos61 = b/h

or, cos61 = b/8

or, b = cos61.8

so, b = 3.9 feet

The bottom of the ladder is 3.9 feet away from the side of the house.

The equation for line p can be written as y= – 5/4 x–6. Line q includes the point (5, – 8) and is parallel to line p. What is th
Elden [556K]

Answer:

y = -(5/4)x - (1 3/4)

Step-by-step explanation:

A line parallel to y= -(5/4)x - 6 will have the same slope, -(5/4), but a different value for the y-intercept, which is -6 in this equation.  This means we can write:

y = -(5/4)x + b

As klong a b is not -6, the line will be parallel.  But we are told that point (5,-8) must be on the new line.  That means we need to select a value of b to make that happen.  By shifting b, we can move the straight line up or down.  To move it so that it goes through (5,8), enter that point in the equation and solve for b:

y = -(5/4)x + b

-8 = -(5/4)*5 + b   for (5,-8)

-8 = -(25/4) + b

b = -8 + (25/4)

b = -(32/4)+(25/4)

b = -(7/4) or - 1 3/4

The parallel line that goes through (5,-8) is y = -(5/4)x - 2
