The figure below shows the design of a truss to support the weight of a roof. In this truss design, ∠A⩭∠D and ĀF⩭DF.

Answer:

$m\angle A= 30^{\circ}$

Step-by-step explanation:

In the question, we're given $\angle A\cong \angle D$ . Therefore, the measure of these two angles must be equal.

To find the value of $x$ , set these two angles equal to each other:

$4x-26=x+16$

Add 26 and subtract $x$ from both sides:

$3x=42$

Divide both sides by 3:

$x=\frac{42}{3}=14$

Since $\angle A$ was labelled as $4x-26$ , substitute $x=14$ to find its measure:

$\angle A=4(14)-26,\\\angle A=56-26,\\\angle A=\boxed{30^{\circ}}$

You can also substitute $x=14$ into the label of angle D as angle A is congruent to angle D for easier calculations ( $14+16=\boxed{30^{\circ}}$ ).

The length of a rectangular prism is 8

Lena [83]

Surface area is:

$W=width$
$L=length$
$H=height$

$S=2*(L*W+L*H+W*H)$

replacing the values

$250=2*(8*W+8*1+W*1)$

$250=2*(8*W+8+W)$

$250=2*(9*W+8)$

dived each member by 2

$125=9W+8$

$9W=125-8$

$9W=117$

$\boxed{\boxed{W=13~unit~of~measure}}$

The volume of a rectangular prism is

$V=L*H*W$

$V=8*1*13$

$\boxed{\boxed{V=104~unit~of~volume}}$

Helpp this is my final

aivan3 [116]

Answer: 6.

Step-by-step explanation:

4^2 = 16

10 − 16 + 6 * 2

6 * 2 = 12

10 − 16 + 12

10 - 16 = -6

-6 + 12 = 6

A chocolate chip cookie recipe ask for one and one half times as much flour as chocolate chips. If three and three quarters cups

babymother [125]

Answer:

1/2 a cup.

Step-by-step explanation:

3.5 times as much flour as chocolate chips....

f = 3.5c

f = 1 3/4 (or 1.75)

1.75 = 3.5c

1.75 / 3.5 = c

0.5 = c......chocolate chips needed would be 1/2 a cup

Hope that helps!
