Answer:
x = 16
Step-by-step explanation:
SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.
The angles opposite to equal sides are equal.
⇒ ∠STR = ∠R
∠STR = 4x - 28
Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair
∠STR + ∠STU = 180° {linear pair}
4x - 28 + 9x = 180
4x + 9x - 28 = 180 {Combine like terms}
13x- 28 = 180
Add 28 to both the sides
13x = 180 + 28
13x = 208
Divide both sides by 13
x = 208/13
Answer:
16
Step-by-step explanation:
Since this is a right triangle, we can use trig identities
sin theta = opp / hyp
sin 30 = 8 / NO
Multiply each side by NO
NO sin 30 = 8
Divide each side by sin 30
NO = 8 /sin 30
NO = 8 / 1/2
NO = 16
Answer:
x = 84
Step-by-step explanation:
The equation is
x - 4 = 24 ( add 4 to both sides )
x = 28 ( multiply both sides by 3 to clear the fraction )
x = 3 × 28 = 84
Answer:
Step-by-step explanation:
Circumference of a circle is
Answer:
Slope:
Y - intercept: -1
Step-by-step explanation:
We can see from the graph that the slope is .
We can also identify the y - intercept as -1.
Therefore, the linear equation would be y = x -1
Hope this helps:) Goodluck!
