The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.
When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck
Answer:
$2.50
Step-by-step explanation:
Since there are 2 pounds in the bag, you simply divide $5.00 by 2 to get the price of a single pound.
<span>RT, i.e. is S the midpoint of RT? If it does, then RS = ST; RT = RS + ST; RT = 2 * RS; RT = 5 1/4</span>
Answer:
B) Multiply each side by 3
Step-by-step explanation:
This is how to solve for h
+ 7 = 5 (First Step --> Subtract 7 from both sides)
= - 2 (Second Step --> Multiply both sides by 3 to cancel out the denominator and to find just h)
h = -6
Answer:
teds sister is 60 years old, ted is 120 some how, and joe is 123.
Step-by-step explanation:
half of a century is 50 because a century is 100 years and plus 10 years equals 60 and 60 times 60 equals 120 and 120 plus 3 years equals 123 so that's how I got the answers. At first this answer looks complicated you just have to read the question carefully.
