<u>Find total number of red card or a 10:</u>
Total number of cards that are red = 26
Total number of cards that are 10 but not red = 2
Total number of cards that are red card or 10 = 26 + 2 = 28

P(red card or a 10) = 28/52 = 7/13

Answer:
The height of the tree is is 60m
Step-by-step explanation:
Let's answer a, as it is the only complete question.
We know that the angle of elevation of the top of a tree observed from a point 60m away, is 45°.
We can model this with a triangle rectangle, a sketch of it can be seen below (assuming that you are looking it from the ground).
You can see that the adjacent cathetus to the 45° angle is equal to 60m
And the opposite cathetus is the measure we want to find.
Now you can remember the trigonometric relation:
tan(a) = (opposite cathetus)/(adjacent cathetus).
So to find the height of the tree we need to solve:
tan(45°) = H/60m
This is just:
tan(45°)*60m = H =60m
The height of the tree is is 60m
Because you’re paying interest first so the faster you pay off the interest the faster you get to the principal and pay the actual debt off
Hard question thx for the points give me brainlest points
