Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle

noting that sin45° = $\frac{1}{\sqrt{2} }$ ← exact value

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{8}{h}$

Multiply both sides by h, then

h × $\frac{1}{\sqrt{2} }$ = 8

Multiply both sides by $\sqrt{2}$

h = 8 $\sqrt{2}$ → D

What is the value for y?<br><br><br><br> Enter your answer in the box.

Anna007 [38]

Answer:

y = 28

Step-by-step explanation:

since this is an Isosceles triangle (x - 5)° must be equal to 34°

x - 5 = 34

x = 39

the sum of interior angles in a triangle is equal to 180°

if the two angles 34 + 34 = 68

Then the third angle is 180 - 68 = 112°

4y = 112

y = 28

Two triangles are similar.The the smaller triangle has side 10,20 and 15 units the larger triangles longest side is 52 units.Wha

Oliga [24]

Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

$k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}$

$k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}$

Length of other two sides,

$10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}$

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

Marcie cooked dinner for herself. The original recipe has a serving size of 4 and requires four and four fifths pounds of chicke

Margarita [4]

Answer:

1.2 pounds of chicken per serving.

Step-by-step explanation:

4 and 4/5 of pounds of chicken for serving of 4.

We can also write this as 4.8 pounds of chicken.

To find how much pound of chicken will be needed for a single serving we have to divide 4.8 by 4.

$\frac{4.8}{4} = 1.2 \: pounds \: of \: chicken$

If this answer helped you, give this answer a heart and rate it.
