Answer:
27
Step-by-step explanation:
If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:
6x-4=25-11, what is the value of 9x?
Let's solve for x first by using the given information: 6x-4=25-11
1. 6x-4=25-11
2. 6x-4=14
3. (isolate x by adding 4 on both sides) 6x=18
4. x=3
The question asks for the value of 9x. Since we know x=3...
9x=9 times 3=27
9x=27

Answer:
x ≈ 77°, y = 103°
Step-by-step explanation:
Using the Sine rule in Δ BCD
=
( cross- multiply )
2.9sinx° = 4sin45° ( divide both sides by 2.9 )
sinx° =
, thus
x =
(
) ≈ 77° ( to the nearest degree )
Since AC and DC are congruent then Δ ACD is isosceles.
Thus the base angles are congruent, that is
∠ ADC = ∠ CAD = y°
x and y are adjacent angles and supplementary, thus
x + y = 180, that is
77 + y = 180 ( subtract 77 from both sides )
y = 103°
