Answer:

27.82 \degree

Step-by-step explanation:

To find the unknown angle use tan rule

\tan( \theta)  =  \frac{opposite}{adjacent}

Let the unknown angle be x

\tan(x)  =  \frac{o}{a}  \\  \tan(x)  =  \frac{19}{36}  \\  \tan(x)  = 0.5277 \\ x =  \tan ^{ - 1} 0.5277 \\ x = 27.82 \degree

Hope this helps you.

Let me know if you have any other questions :-):-)

Ginny's piggybank contained $8.80 in quarters, dimes, and nickels. there were two more than five times as many nickels as quarte
SSSSS [86.1K]

Answer:

There are 13 quarters, 67 nickels, and 22 dimes.


Step-by-step explanation:

The value of a quarter is $0.25, the value of dime is $0.10, and the value of a nickel is $0.05. Let there be q quarters, n nickels, and d dimes.

Let's write equations from the statements given:


<u>"Ginny's piggybank contained $8.80 in quarters, dimes, and nickels.":</u>

0.25q+0.1d+0.05n=8.80

<u>"there were two more than five times as many nickels as quarters":</u>

5q+2=n

<u>"4 less than twice as many dimes as quarters":</u>

<u>2q-4=d</u>


Plugging in equation 2 and 3 into equation 1, we can solve for q:

0.25q+0.1(2q-4)+0.05(5q+2)=8.80\\0.25q+0.2q-0.4+0.25q+0.1=8.80\\0.7q=8.80+0.4-0.1\\0.7q=9.1\\q=\frac{9.1}{0.7}=13

<em>Substituting q = 13 into equation 2 will give us nickels:</em>

n=5q+2\\n=5(13)+2\\n=67

<em>Substituting q = 13 into equation 3 will give us dimes:</em>

d=2q-4\\d=2(13)-4\\d=22


There are 13 quarters, 67 nickels, and 22 dimes.

What is the value of x is?
marin [14]
The applicable theorem is the one that tells you the exterior angle is equal to the sum of the opposite interior angles.
  9x = (5x) +(9 +x)
  9x = 6x +9 . . . . . . . . collect terms
  3x = 9 . . . . . . . . . . . . subtract 6x
  x = 3 . . . . . . . . . . . . . divide by 3

The value of x is 3.

_____
The angles (clockwise from left) are then
  (9*3)° = 27°
  (5*3)° = 15°
  (9 +3)° = 12°
This is an obtuse triangle, obviously not drawn to scale.

Jose worked n hours at 8.75 dollars per hour he made a total of $61.25 write an expression that represents the total number of h
Nitella [24]

Answer:

n = P/8.75

Step-by-step explanation:

Jose’s pay (P) depends on the number (n) of hours he works.

P = 8.75n     Divide both sides by 8.75

n = P/8.75

=====

P = $61.25

n = 61.25/8.75

n = 7 h

Jose worked for 7 h.
