We can get QN by Pythagorean theorem:
QN = √24² + 3² = 24.19
We can get angle NQP by:
tan NQP = 3/24
NQP = 7.13°
With this, we can get angle MQN
MQN = 90 - 7.13
MQN = 82.87°
By cosine law, we can get MN
MN = √[10² + 24.19² - 2(10)(24.19) cos82.87]
MN = 25 in
Looking at number 4, you first have to look at the information that you have:
On tuesday he practiced for 1 5/6 hrs
Monday he practiced for 7/10 hrs
He is supposed to practice for 1 1/4 hr.
You could write questions like:
How much more did Marco practice on Tuesday than he is supposed to practice?
This works because it does indeed involve subtraction, you would be subtracting the amount that he should have practiced from the amount of time that he did practice.
If I didn't answer the question, please message me and I will clarify!
Answer: 585 maybe??
Step-by-step explanation:
450/100 = 4.5
4,5 = 1 percent of the total amount.
4.5 x 25 = 112.5
112 = 25 percent of 450
4.5 x 5 = 22.5
22.5 = 5 percent of 450
Hope u understand and that this helps:)
Answer:
As described in picture:
RPS = 5x + 34
QPR = 8x + 15
RPS +QPR = QPS = 88
=>5x + 34 + 8x + 15 = 88
=> 13x + 49 = 88
=> 13x = 39
=> x = 3
=> RPS = 5 x 3 + 34 = 15 + 34 = 49 deg
Hope this helps!

Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right
