So, the first blank is for what kind of angle it is: acute, obtuse, reflex, straight, or right. The second blank is for what the measure of the angle is. You can find that out by looking at the protractor. It should tell you what the measure of the angle is. You can read the protractor by looking at the numbers. The numbers are the degrees of incline the angle measures, which is what you're looking for.

What is the error in this problem

Answer:

10). m∠x = 47°

11). x = 30.96

Step-by-step explanation:

10). By applying Sine rule in the given triangle DEF,

$\frac{\text{SinF}}{\text{DE}}=\frac{\text{SinD}}{\text{EF}}$

$\frac{\text{Sinx}}{7}=\frac{\text{Sin110}}{9}$

Sin(x) = $\frac{7\times (\text{Sin110})}{9}$

Sin(x) = 0.7309

m∠x = $\text{Sin}^{-1}(0.7309)$

m∠x = 46.96°

m∠x ≈ 47°

11). By applying Sine rule in ΔRST,

$\frac{\text{SinR}}{\text{ST}}=\frac{\text{SinT}}{\text{RS}}$

$\frac{\text{Sin120}}{35}=\frac{\text{Sin50}}{x}$

x = $\frac{35\times (\text{Sin50})}{\text{Sin120}}$

x = 30.96

Solve for x. ( Help pls !! also round to the nearest hundredths which is to places after the decimal)

The answer would be 10 because the full side is 20 and it’s only asking for half the side so it would be 10
