Answer:

Step-by-step explanation:

Since if it's 5 or higher you go up but if it's 4 or lower you stay the same. And since 2.36 doesn't have the .5 it would round to 2

Answer:

Step-by-step explanation:

The rounding rule is 5 or higher round up and below 5 round down. So we're rounding to the nearest whole numbers so we have to look at the tenths place. Since the tenths place number is below 5 we round down to 2.

In the figure shown the value of a is equal to

Vikentia [17]

Answer:

a = 7.2

Step-by-step explanation:

The figure has been re-labelled and attached to this response.

From the figure, the larger right triangle DAB and the small right triangle BCA are similar. This is because;

i. They have two corresponding congruent angles which are the right angle

and angle B

Therefore, we can say that;

$\frac{|DB|}{|BA|} = \frac{|AB|}{|BC|}$

$\frac{13}{a} = \frac{a}{4}$

Cross multiply

a x a = 13 x 4

a² = 52

a = √52

a = 7.2

Note: The figure showing the similar triangles has also been attached to this response.

Given mn, find the value of x. 108

adoni [48]

Answer:

72 degrees

Step-by-step explanation:

Referencing off of line t being a straight line, a straight line is 180 degrees. If you subtract 108 from 180, you would get 72. Since this intersecting line is going through 2 paralel lines, the 2 groupings of angles reflect each other.

Three less than 5 times a number is less than or equal to 12. If the number is a whole number, what could the number be?:

PIT_PIT [208]

Answer:

Step-by-step explanation:

4x2=8

5x2=10

6x2=12

This answer is the closest to 12 but it doesn't go over 12, so this is less than or equal to 12

Identify the postulate that proves the triangles are congruent.

Ratling [72]

Answer:

ASA

Step-by-step explanation:

Triangle ABD is congruent to triangle BDC by ASA because angle B in ABD is 30 degrees. Then they give you BD which equals BD by the reflexive property. And finally angle D in ABD is also 30 degrees. In triangle BCD, angle B is 30 degrees, BD = BD, and angle D in BCD is 30 degress. So we have an angle (B), side (BD), and another angle (D)
