Answer:
X = 5 unit
Step-by-step explanation:
Given as , ABC is a Triangle ,
AC extended to through C to D
∠BAC = 6x + 10
∠ABC = 6x - 10
∠BCD = ∠ 8x + 20
When c extended to D then , ∠BCD is an external angle
∵ <u>External angle = Sum of opposite internal angles</u>
Or ,∠BCD = ∠BAC + ∠ABC
Or, ∠ 8x + 20 = 6x + 10 + 6x - 10
Or, ∠ 8x + 20 = 12x
Or, 12x - 8x = 20
∴ 4x = 20
So, x = 
= 5
Hence the value of X = 5 unit Answer
Answer:
Step-by-step explanation:
so 20% of the total price equals $ 30
let x represent the total price
turn ur percent to a decimal
0.20x = 30
x = 30 / 0.20
x = 150 <=== total price
Answer:
12 =x
20.78460969=y
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin 60 = y /24
Multiply each side by 24
24 sin 60 = y/24*24
24 sin 60 =y
20.78460969=y
cos theta = adjacent side / hypotenuse
cos 60 = x /24
Multiply each side by 24
24*cos 60 = x/24*24
24 cos 60=x
12 =x
A right angle measures an angle exactly 90 degrees, obtuse= more than 90, acute less than 90 degrees. Triangle angles add up to 180 degrees quadrilaterals measure up to 360 degrees. A fraction can be written as a decimal or percent answer. A fraction is not a whole number. The reciprocal is the opposite of that number/ fraction. Pls give brainliest.
