5x + 5 = 90°
5x = 85°
x = 17°
The value of x is 17° due to the pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.
We have been given that the pair of angles as
(3x + 1)° and (4 + 2x)°
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So 3x + 1 + 4 + 2x = 90°
⇒ 5x + 5 = 90°
⇒ 5x = 85°
⇒ x = 17°
Therefore, the value of x is 17°.

Use trigonometry.
sin x = opposite ÷ hypotenuse
sin x = 7/9
Take the arcsin on both sides.
arcsin(sin x) = arcsin(7/9)

Step-by-step explanation:
.05N + .10D = 1.65
.05 is the value of the nickel and .10 is the value of the dime.
N + D = 21 because you have some combination of them that total 21
solve for N: N = 21- D
substitute into the first equation
0.5 (21-D) + .10D = 1.65
1.05 - .05D + .10D = 1.65
.05D = .6
D = 12 you have 12 dimes
21-12 = 9 nickels

14/1 = x/1.99 what is this awnswer
Answers
Answer:
x = 27.86 thats the answer
Answer:
0.2786
Step-by-step explanation:
Solution Steps:
The following question is of the type "How much X percent of W", where W is the whole amount and X is the percentage figure or rate".
Let's say that you need to find 14 percent of 1.99. What are the steps?
Step 1: First determine the value of the whole amount. We assume that the whole amount is 1.99.
Step 2: determine the percentage, which is 14.
Step 3: Convert the percentage 14% to its decimal form by dividing 14 into 100 to get the decimal number 0.14: 14100 = 0.14
Notice that dividing into 100 is the same as moving the decimal point two places to the left. 14.0 → 1.40 → 0.14
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount: 0.14 x 1.99 = 0.2786 (answer).
The steps above are expressed by the formula: P = W × X% 100. This formula says that: "To find the portion or the part from the whole amount, multiply the whole by the percentage, then divide the result by 100". The symbol % means the percentage expressed in a fraction or multiple of one hundred.
