Answer:
36.45
Step-by-step explanation:
tan 32 = a/35
x = 23.1
tan 70 = b/23.1
y = 28.2
x^2 = a^2+b^2
= 23 .1^2 + 28.2^2
= 36.45
Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
I don't know the answer I need help on it as well
