<u>Answer:</u>
<u>Step-by-step explanation:</u>
To find the missing side of a right-angled triangle, first look at the given angle, and notice its relationships with the given and required sides.
In this case:
• The side adjacent to the given 38° angle is (required).
• The hypotenuse is 30 units.
The trigonometric ratio that relates the adjacent side and hypotenuse of a triangle is cosine (cos), where:
.
Substituting into the formula:
⇒
⇒
Answer:
14/24 and 3/24
Step-by-step explanation:
There are 50 stack.
10 in each stack.
10 multiplied by 50
10×50=500
Answer:
Upper left: the answer is 2, becuase 2 times 5x = 10x
Upper right: the answer is 4y, because 6 times 4y = 24y
Lower left: the answer is 3, because 3 times 3a+2b = 9a+6b
Lower right: the answer is 3a+2b, because 4 times 3a+2b =12b+8b
