Answer:
x = 30
2x =60
Step-by-step explanation:
the angle is a right angle- so that means it’s a 90 degree angle
so let’s set up an equation..
We get 90 degrees when we add 2x Plus x
So 2x + x = 90
then, 3x = 90
x= 30
you Can check your Answer by:
Do 2 times 30 = 60
and then 60+ 30
you will Get 90
The perimeter is all the sides added up.
s1+s2+s3+s4= p
So, 12+ 6+ 8+ 17= the perimeter.
12+6+8+17 = 43
The answer is 43.
I hope this helps!

C) 90.16
sin (48°) = 67 / x
x • sin (48°) = 67
x = 67 / sin (48°)
x = 90.16
No problem!

Answer:
1) P(tacos)= 10/30= 1/3
2) P(Pizzas)=18/30 =3/5
3) P(T AND P)= 5/30= 1/6
4) P(T OR P)= P(T) +P(P) - P(T AND P)
= 10/30 +18/30 -5/30
= 23/30
Answer: 15 mph
Step-by-step explanation:
Given: Time taken to travel uphill to the toy store= 12 minutes![=\frac{12}{60}=0.2\ hour](https://tex.z-dn.net/?f=%3D%5Cfrac%7B12%7D%7B60%7D%3D0.2%5C%20hour)
Let d be the distance(in miles) between the home and toy store.
Also,
![\\\Rightarrow10=\frac{d}{0.2}\\\Rightarrow\ d=0.2\times10=2](https://tex.z-dn.net/?f=%5C%5C%5CRightarrow10%3D%5Cfrac%7Bd%7D%7B0.2%7D%5C%5C%5CRightarrow%5C%20d%3D0.2%5Ctimes10%3D2)
Thus, distance from home to toy store= 2 miles
When she turn back, to home distance remains same.
The time taken by her to come back at 30 mph speed=
![Time=\frac{Distance}{speed}=\frac{2}{30}=\ hour](https://tex.z-dn.net/?f=Time%3D%5Cfrac%7BDistance%7D%7Bspeed%7D%3D%5Cfrac%7B2%7D%7B30%7D%3D%5C%20hour)
Now, the average speed =![\frac{\text{Total distance}}{\text{Total time}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BTotal%20distance%7D%7D%7B%5Ctext%7BTotal%20time%7D%7D)
![=\frac{2+2}{0.2+\frac{2}{30}}\\=\frac{4}{\frac{6+2}{30}}\\=\frac{4\times30}{8}=\frac{120}{8}=15\ mph](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%2B2%7D%7B0.2%2B%5Cfrac%7B2%7D%7B30%7D%7D%5C%5C%3D%5Cfrac%7B4%7D%7B%5Cfrac%7B6%2B2%7D%7B30%7D%7D%5C%5C%3D%5Cfrac%7B4%5Ctimes30%7D%7B8%7D%3D%5Cfrac%7B120%7D%7B8%7D%3D15%5C%20mph)
