Answer:
The flag pole is 28 feet
building is 168 feet
Step-by-step explanation:
building+flagpole= 196 feet
(use algebra)
let the flagpole be a
building will be 6a
<h2>
so 6a+a= 196</h2>
7a= 196 = 28
it means the flag pole is 28feet
28×6 is the building= 168 feet
Step-by-step explanation:
In ∆ABC, if <A is 90° and <B is 45° then hypotenuse is BC.
Now,
Cos B= base/height
Cos B= AB/ BC
BC= AB/cos 45°.
Answer:
10
Step-by-step explanation:
number of slices = 6 slices
amount each student receives = 3/5 slice per student
number of students
= number of slices / number of slices per student
= 6 ÷ (3/5)
= 6 x (5/3)
= 30/3
= 10 students
If the triangle is a right triangle, then
(3x)² + x² = (10)² .
9x² + x² = 100
10x² = 100
x² = 10
x = √10 = approx. 3.1622...
If ' x ' is <em>anything less than √10</em> , then the short sides are too short
to make a right angle at the top, and the angle where they meet
is obtuse.
' x ' has to be greater than 2.5 ... otherwise the two short sides
can't stretch far enough to reach both ends of the long side (10) .
So, if 2.5 < x < √10 , then there is a triangle, and it's obtuse.
3w. you find common factor for each. For 12 and 15 it is 3. For w and wz it is w. Combine them together you get the answer.
