A^2 + b^2 = c^2
9^2 + 12^2= c^2
81 + 144 = 225
C= 15
The answer is 15 yards.

Answer:

Hi there!

The correct answer will be 15 yd

Step-by-step explanation:

There are two ways you can go about solving this problem

Method One: Pythagorean Theorem

a^2 + b^2 = c^2 then all you have to do is plug in the values

(12)^2 + (9)^2 = c^2 you should get c^2 = 225 then you square root both sides and you get c = 15

Method Two: Pythagorean Identities

This triangle represents a 3,4,5 triangle

All the sides just tripled so that means the hypotenuse is 5*3 which equals 15

Answer:

Step-by-step explanation:

2(2x +4) - 2x = x + 18

4x +8 -2x = x +18

2x -x = 18-8

X = 10

Put the value of x in both side

Left side *+*+*+*+*+

2 ( 2*10+4)-2*10

48-20 = 28

Right side +*+*+*+*+*

X + 18

10+ 18 = 28

First, 9.8 (Gravity) times 3 (time) equals 29.4, which is the velocity after 3 seconds. The kinematic equation for change in position that uses the variables we have is:
delta x= (v)(t) -0.5(acceleration)(time)^2
delta x= 29.4 times (3) - 0.5 (9.8) times 9
delta x= 44.1
100 minus 44.1 equals 55.9, which is the answer for part a.

Tell me if you need any clarification

PART B:
The kinematic equation for this is:
delta x= (initial velocity) times time plus 0.5 (a)(time)^2
100=(0)times(x) plus 0.5 (a)(time)^2
100=0.5(9.8)(x)^2
100=4.9x^2
100/4.9 is approxamitely 20.4.
The squareroot of this is approxamitely 4.5.

Nora measured the angles of a triangle. Two of the angles measured 20° What was the measure of the third angle of Nora’s triangl

aivan3 [116]

Answer:

140°

Step-by-step explanation:

The sum of angle of a triangle is equal to 180°.

Two of the angles measured 20°.

We need to find the measure of the third angle of Nora’s triangle. let the third angle is x. So,

20+20+x = 180

40+x = 180

x = 180-40

x = 140°

So, the third angle of the triangle is 140°.
