Answer:
b=18
a=6√18
Step-by-step explanation:
tan 45=b/18
by cross multiply
b=tan 45×18
=1×18
=18
find (a) by using pythagora's theorem
a^2=18^2+18^2
=324+324
a^2=648
take square root both sides
√a^2=√648
a=√36×18
a=6√18
The appropriate response is the third one. A Cartesian organize framework is an arrange framework that determines each point exceptionally in a plane by a couple of numerical directions, which are the marked separations to the point from two settled opposite coordinated lines, measured in a similar unit of length. Each reference line is known as an organize pivot or only hub of the framework, and the point where they meet is its birthplace, as a rule at requested combine (0, 0).
Answer:
Step-by-step explanation:
Let's say BE is x then:
x^2 + 18^2 = (24 - x)^2
==> x = 5.25
BE = FD == x
==> FD = 5.25
This is harder than it looks I cant figure it out
Answer: 4
Step-by-step explanation:
All you have to do is multiply each number 14 * 4 = 56 : 16 * 4 = 64 : and 7 * 4 = 28
