Answer:
67.9
Step-by-step explanation:
The polygon has 6 sides.
Sum if interior angles = (n-2)180
=(6-2)180
= 4 x 180
= 720
A + B + C + D + E + F = 720
x+40 + 2x-9 + 2x + 2x + x + x+78 = 720
9x + 109 = 720
9x = 720-109
9x = 611
x = 611/9
x = 67.9

The proper angle for a ladder is about 75' from the ground. Suppose you have a 21 foot ladder. How high
can it reach?
Answers
The ladder gets propped against the house, making a 75 degree angle with the ground. We can use the fact that cos(75°)=base distance/length of ladder to figure out the length of the base. Multiplying both sides by length of ladder we get, length of ladder×cos(75°)=base distance.Nov 6, 2019

Answer:
The angle x, has the measurement of 40°
Step-by-step explanation:
Step 1: Define complementary angles
Complementary Angles: Two angles are complementary when the sum of them is equal to 90°. For example, 30° and 60° are complementary because they add up to 90°.
Step 2: Figure out the complementary angle
Since ∠ABD and ∠DBC are complementary, that means that they should add up to 90°. Since the angle value of ∠ABD is 50°, that means that the angle value of ∠DBC should be 90° - 50° = x.
90° - 50° = x
40° = x
Answer: The angle x, has the measurement of 40°

What is the measure of < c in quadrilateral ABCD?
Answers
Answer:
the sum of interior angles of a quadrilateral = 360 degree
Step-by-step explanation:
therefore,
let the angle C be X
124 + 96 + 94 + X = 360
314 + X = 360°
X = 360 - 314 = 46°
angle C = 46°

NEED HELP ASAP 2 questions WORTH 50
Answers
Answer:
The first question tan(24) = x/12 because tan(x) = opposite/adjacent
so x in radians ≈ -25.618....
x in degrees ≈ 5.342....
For the second question tan(72) = x/20
x in radians ≈ -5.248....
x in degrees ≈ 61.553....
Answer:
for first one
relationship between base and perpendicular is given by tan angle
tan24=p/b
tan24=x/12
x=tan24×12=5.34
Step-by-step explanation:
for second one
relationship between base and perpendicular is given by tan angle
tan72=x/20
x=tan72×20=61.55

Determine whether the equation has one solution, no solution, or infinite solutions.
Explain your reasoning.
9x + 2 = -4(x + 6)
Answers
Answer:
The equation has 1 solution.
Step-by-step explanation:
Because you don't get the same answer on both sides, this equation does not have infinately many solutions. Because you don't get an invalid answer, such as 1 = 0, this equation doesn't have one solution. When you solve this equation, you'd get something similar to this
9x-2 = -4x-24 (distributive property)
13x-2=-24 (combine like terms)
13x=-22 (additive property of inversion)
x = -22/13
which is a valid, real-world solution.
