Answer:
No thanks
Step-by-step explanation:
Theta has a reference angle of 30° and is in Quadrant I or II.
Sin(theta) = ½
Basic angle: 30
<h3>What is the reference angle?</h3>
The acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle sandwiched between the terminal side and the x-axis.
Angles: 30,
180-30 = 150
Because sin is positive in quadrants 1 and 2.

Isolating variables mean to get the variable, or the letter all by itself by doing something to get rid of the number/numbers that are on the same side. That way you can solve for that missing variable.
Answer:
<h2>answer: 390</h2>
Step-by-step explanation:
To find area for triangles you do
base × height ÷ by 2 So... 30 × 26 = 780
780 ÷ 2 = 390 so the area of this triangle is 390
Multiply 3 * 1 1/2 to find how many miles she runs per hour
1 1/2 * 3
3/2 * 3
9/2
4 1/2 She will run 4 1/2 or 4.5 miles per hour.
