Step-by-step explanation:
there are 13 cards per 4 suits, totalling 52 cards in an entire deck
13 represents an entire 1 suit out of 52 cards
13/52 = 0.25
thus your answer is 0.25% or 1/4
Answer:
top one =75
bottom one=65
Step-by-step explanation:
all angles should equal to 180
so 180-40=140
the sum of th eother two angles will be 140
so 4x-5+3x+5=140
now solve for x
x=20
subsitute for x
4(20)-5=75
3(20)+5=65
please mark brainliest if correct
Answer:
y= 77° x=103°
Step-by-step explanation:
x=103° Alternate angles are equal
y=77° angles on a straight line sum to 180° (180°-103°=77°)

Answer:

Step-by-step explanation:
Hi there!
<u>1) Find the length of the other leg in the right triangle</u>
There are two ways we can go about this. The first way is to use trigonomic ratios:
We're given one of the legs and we're trying to solve for the other, so we can use the tangent ratio:
![tan\theta=\frac{opp}{adj}](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cfrac%7Bopp%7D%7Badj%7D)
Let x be equal to the length of the other leg. Plug in the known values:
![tan45=\frac{x}{7}\\7*tan45=x\\x=7](https://tex.z-dn.net/?f=tan45%3D%5Cfrac%7Bx%7D%7B7%7D%5C%5C7%2Atan45%3Dx%5C%5Cx%3D7)
The other way to find this is to observe the angles. Because we're given that two of the angles are 45 and 90 degrees, we know that the third angle is 45 degrees. This makes this an isosceles triangle, meaning the other leg is 7 ft long.
<u>2) Determine the height of the hoop</u>
Add 7 ft and 5 ft (the person's height):
7+5=12 ft
I hope this helps!
