Answer/Step-by-step explanation:

The rhombus when split into two triangles will give us two equilateral triangles that are congruent to each other.

Therefore:

The two bases of both triangles will have equal angle measures of 4x + 5 each and a third angle measure of 8x - 6.

✅Formula to find the value of x:

(8x - 6) + 2(4x + 5) = 180° (sum of triangle)

8x - 6 + 8x + 10 = 180

8x + 8x - 6 + 10 = 180

16x + 4 = 180

16x + 4 - 4 = 180 - 4

16x = 176

16x/16 = 176/16

x = 11

Hey I’m struggling with number 13 so please show your work. Thx
Dafna11 [192]

Answer:

\frac{5}{12}

Step-by-step explanation:

Because \frac{3}{5} is being multiplied by S, we can divide \frac{3}{5} from both sides of the equation. This will give us:

\frac{1}{4}÷\frac{3}{5}

But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of \frac{1}{4}÷\frac{3}{5}, you get:

\frac{1}{4}×\frac{5}{3}

When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.

By doing that, you get the fraction \frac{5}{12}

\frac{5}{12} cannot be simplified any more, so S=\frac{5}{12} is your answer :)

I hope this helps
