Write a conditional statement that correctly describes each venn diagram in the space provided?
MakcuM [25]
Remember that a conditional statement (p→q) is an if-then in which the first part, p, is the hypothesis and the second part, q, is the conclusion. 

1. Here the set m<span>∠A=40° is a subset of the set Acute Angles, so </span>m∠A=40° is the hypothesis and Acute Angles is the conclusion. 
In other words:
m∠A=40°→∠A is an Acute Angle 
if m∠A=40°, then ∠A is an Acute Angle

We can conclude that the conditional statement that describes the Venn diagram is: if m∠A=40°, then ∠A is an Acute Angle

2. Just like before, the set 2x=4 is a subset of the set x=2; therefore, 2x=4 is the hypothesis and x=2 is the conclusion.
In other words:
2x=4→x=2
if 2x=4, then x=2

We can conclude that the conditional statement that describes the Venn diagram is: if 2x=4, then x=2

(Two office buildings are 51 m apart. The height of the taller building is 207 m. The angle of depression from the top of the ta
Sholpan [36]
See the attached figure to better understand the problem

we know that

in the triangle ABC
tan 15=AC/BC--------> AC=BC*tan 15
BC=51 m
AC=51*tan 15------> AC=13.67 m

t<span>he height of the shorter building=207-AC----> 207-13.67----> 193.33 m
</span>the height of the shorter building=193 m
<span>
the answer Part a) is
</span>the height of the shorter building is 193 m
<span>
Part b) </span><span>how does the angle of depression from the top of the taller building relate to the angle of elevation from the top of the shorter building
</span>
we know that

the angle of depression is equals to the angle of elevation
so

the answers are
<span>A:They are congruent
</span><span>D:They are alternate interior angles</span>

\large \mathfrak{Solution : }

As we know :

Dividend = Divisor × Quotient ( taking remainder as 0 )

So, Quotient = Dividend ÷ Divisor

by using the above relation we can say :

  • q = t ÷ 23

therefore, correct option is C. t ÷ 23
