Can someone me with. im not good at this stuff. i will give you 18 points with brainliest.

Exercise 3

Note that HJI is a right triangle. So, the angle HIJ (which is the same as HIG) is acute, because the sum of the interior angles of any triangle is 180, and since HJI is right, the two other angles must sum up to 90, and so they can't be more than 90.

Exercise 4

The draw suggests that HJ is perpendicular to JI, because it is its height. So, the angle between HJ and JI is right.

#3: Acute.

#4: Right

Here's why: Same as last question. Acute is an angle SMALLER then 90 degrees. Obtuse is an angle LARGER than 90 degrees, and right is an angle EXACTLY 90 degrees.

Hope that helps!

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
