Answer:

a) Plots are similar
b) x= 5577 feet

Step-by-step explanation:

<em>Refer to attached</em>

<h3>Question</h3>

a) Are the plots of land similar?
b) Find to the exact value of x and rounded to the nearest tenth?

<h3>Solution</h3>

The small triangle have missing angle of 180° - (52° + 58°) = 70°

This is indicating both triangles have same 3 angle measures.

Since all angles are same, the triangles are similar.

<u>Corresponding sides, against corresponding angles are:</u>

6180 and 8240
x and 7436

<u>As per property of similarity, the ratio of corresponding sides is same</u>

6180/8240 = x/7436
x = 6180*7436/8240
x = 5577 feet

When 5 is added to a set of 3 numbers the mean increases to 4.6. What was the mean of the original 3 numbers?

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Multiply 4.6 by 4 to get the sum of the numbers after 5 was added:

4.6 x 4 = 18.4

^ This is the new total

Subtract 5 from this:

18.4 - 5 = 13.4

Divide this value by 3 to get the original mean:

13.4/3 = 67/15

Jason has 208 baseball cards. This is 52 less than the number of cards that Robert has.

V125BC [204]

Answer:

B) R - 52 = 208

Step-by-step explanation:

Robert has 52 more cards than Jason, who has 208, so Robert has 208 + 52 cards. This can be turned into:

R = 208 + 52

then subtract 52 from both sides:

R - 52 = 208 + 52 - 52

R - 52 = 208

and that's the answer

1 and 2 are supplements, 3 and 4 supplements and 1 =4. prove 2=3<br>

Ne4ueva [31]

Step-by-step explanation:

Supplementary angles are angles that have the sum of their angles to be 180°. Hence if <1 and <2 are supplements, then <1+<2 = 180°.... 1

Similarly if <3 and <4 are supplements, then <3+<4 = 180° ....... 2

Equating the left hand side of both equations since they are both equal to 180°, we will have;

<1+<2 = <3+<4 ....... 3

From the question we are told that <1 = <4, substituting this condition into equation 3;

From 3; <1+<2 = <3+<4

<4+<2 = <3+<4 (since <1 = <4)

subtract <4 from both sides

<4+<2 -<4= <3+<4 -<4

<2 = <3 (Proved!)
