Answer:

125 feet

step by step explanation:

i dont know how to explain it but you have to draw a line in the box where the shape is creating a small other rectangle if that makes sense. so it breaks it into 2 shapes, one that is 9 by 10 and one that is 5 by 7 because 16 - 9 is 7. its sounds confusing but 125 is the answer

They will need 125 square feet

You have to find the area of the total which will be :
16 x 10 = 160 square feet

Then find the small area that is missing
5 x 7 = 35 square feet

Subtract: 160 - 35 = 125 square feet

A triangle has side lengths of 9 in, 13 in, and 20 in. What is the measurement of this triangle's largest angle?
Rama09 [41]

1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :

     i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.

      ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:

       a^{2}=b ^{2}+c ^{2}-2bc(cosA)

2.

20^{2}=9 ^{2}+13 ^{2}-2*9*13(cosA)&#10;&#10;400=81+169-234(cosA)   150=-234(cosA)&#10;&#10;cosA=150/-234= -0.641

3. m(A) = Arccos(-0.641)≈130°,

4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc

The plans for a shed call for a rectangular floor with a perimeter of 204 ft. The length is two times the width. Find the length
Harlamova29_29 [7]
A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68

a=68->length
b=34->width

Which criterion can be used to prove abc and adc are congruent? triangles, abc and acd, are plotted on a grid that share a commo
RUDIKE [14]

The correct answer is option D which is ASA ( Angle - Side - Angle).

<h3>What is congruency?</h3>

If two triangles are congruent, this means they are the same shape and the same size. By definition, all corresponding angles of two congruent triangles are congruent. Additionally, all corresponding sides of two congruent triangles are congruent.

In triangles ABC and ADC,

Angles BCA and DAC are congruent (from the diagram);

Angles BAC and DCA are congruent (from the diagram);

AC is congruent AC (by reflexive property).

So, the triangles ABC and CDA are congruent with the ASA postulate.

ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

Therefore the correct answer is option D which is ASA ( Angle - Side - Angle).
