Suppose a triangle has two sides of length 3 and 4 and that the angle

rodikova [14]

Answer:

Step-by-step explanation:

We can use the law of cosinse:

$c^{2}$ = $a^{2} + b^{2}$ − 2ab cos(C)

Suppose the two sides are a and b, and the angle betweent them is C.

$c^{2}$ = $3^{2} + 4^{2}$ − 2*3*4 cos(60)

We can simplify this to get $c^{2}$ =25-12=13

c= $\sqrt{13}$

Find the value of the variable and GH if H is between G and I. GI=5b+1, HI=4b-5, HI=7

fgiga [73]

Answer:

The value of the variable 'b' is 3 and GH is 9

Step-by-step explanation:

Given:

$GI = 5b+1\\\\HI=4b-5\\ \\HI=7$

H is between G and I

Such that G - H - I

To Find:

GH = ?

Solution:

On Substituting HI we get

$4b-5=7\\\\\therefore 4b=7+5=12\\\\b=\dfrac{12}{4}=3$

Substituting 'b' in HI and GI we get

$HI=4\times 3 -5=12-5=7\\\\\therefore HI = 7$

$GI=5\times 3 +1=15+1=16\\\\\therefore GI = 16$

Now, by Line Addition Property we get

$GI=GH+HI$

Substituting 'HI' and 'GI' we get

$16=GH+7\\\\\therefore GH=16-7=9$

The value of the variable 'b' is 3 and GH is 9

A clipboard costs $2.23. It costs $0.58 more than a notebook. Sheila bought two clipboards and one notebook. She paid with a ten

Troyanec [42]

Hey! So, you know she bought two clipboards. You're going to want to add 2.23 and 2.23 together, which is 4.46. Sheila only bought one notebook, so you simply add 4.46 and 0.58 together, which is 5.05. But, wait! She paid with a 10 dollar bill. Now, we have to take 5.05 out of 10.00, which is 4.95. Now, our answer is going to be $4.95 in change. I hope I helped! :)
