X - age of Tim 5 years ago
x+5 -age of Tim now
(x+5)*3- Tim's mom 5 years ago
(x+5)*3+5 - Tim's mom now
x+5 +(x+5)*3+5 Tim and his mom together now
x+5 +(x+5)*3+5=45
x+5+3x+15+5=45
4x+25=45
4x=20
x=5

(x+5)*3+5 - Tim's mom now
(5+5)*3+5= 10*3+5=35 Tim's mom now

Answer:

128°

Step-by-step explanation:

x + 154° + 78° = 360° {being complete turn}

x + 232° = 360°

x = 360° - 232°

x = 128°

There were n signers of the Declaration of Independence. The oldest was Benjamin Franklin, who was y years old. 7 is 10% of y an

zvonat [6]

Assuming n is the number of signers.

7 is 10% of y.
7 = 0.1y
y = 70

n is 80% of y
n = 0.8y
n = 0.8(70)
n = 56
56 signers

Find the measure of the missing sides in each special right triangle. Simplest radical form

lapo4ka [179]

Answer:

X= $8\sqrt{2}$ Y= $7\sqrt{2}$

Step-by-step explanation:

The first one is 45-45-90 right angled isosceles triangle.

The length of the hypotenuse ie.X can be found with the help of Pythagoras Theorem.

$a^{2} + b^{2} = X^{2}$

where a and b are the remaining sides of the triangle,

$8^{2} +8^{2} =X^{2} \\2*8^{2} =X^{2}\\X=8\sqrt{2}$

X= $8\sqrt{2}$

In the second triangle we have to apply trigonometry,

cos θ= $\frac{Length OfAdjacentSide}{LengthOfHypotenuse}$

cos 30°= $\frac{\sqrt{3} }{2}$

$\frac{\sqrt{3} }{2}$ = $\frac{Y}{14}$

Thus, Y= $7\sqrt{2}$ inches
