Calculate the value of the exterior angle

Mathematics
1 answer:
marishachu [46]3 years ago
6 0

An exterior angle of the triangle equals to the sum opposite interior angles, so

8x+15 = (4x+5) + (3x+20)

8x +15 = 7x +25

x=10

Now, we can calculate the exterior angle.

8x+15 = 8*10 + 15 = 80+15 = 95

Answer is 95⁰.

HELP ASAP HELP PLZ!!!!!!!!!!<br><br> if pic don't come thru wait for me to edit it
Vanyuwa [196]
Your answer will be the 1st one because it says the distributice property and that is when you multiply a number outside a parenthesis and the number one shows that and also as the right numbers, because 2 fits in 34 seventeen(17) times and 2 fits in 16 eight(8) times, so your answer would be 2(17+8)

Hope this helps

A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble. HINT (See Example 7.] H
Murljashka [212]

Answer:  35

Step-by-step explanation:

Given : A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble.

Total = 4+2+1+3+1=11

To find sets of four marbles include none of the red ones, we need to exclude red marbles when we count the total number of marbles.

Then, the total marbles(exclude red) =11-4=7

Now, the combination of 7 marbles taking 4 at a time is given by :-

^7C_4=\dfrac{7!}{4!(7-4)!}=\dfrac{7\times6\times5\times4!}{4!3!}=35

Hence, the number of sets of four marbles include none of the red ones = 35

True or false 120% of a whole number is always greater than the number? and why?
Stells [14]
I can only use math to explain it. What is 100%?
100% = \frac{100}{100} 
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = \frac{120}{100} * 10 = 12
is it greater than 10.

Find the slope of the tangent line to the graph of f at the given point. f(x) = x√ at (36,6) 1/3 1/12 3 12
Alik [6]

slope = \frac{1}{12}

the slope is the value of f' (36)

f(x) = √x = x^{\frac{1}{2} }

f'(x) = \frac{1}{2} x^{-\frac{1}{2} } = \frac{1}{2\sqrt{x} }

f'(36) = \frac{1}{2(6)} = \frac{1}{12}
