<u>❒ Required Solution:</u>

  • We are here to find the three angles with the help of the angle sum property (Sum of the angles of a triangle = 180°). So, using this property we can find all the angles.

<u>❍ According to the question :</u>

\\ \tt \implies \: 60{}^{ \circ} + 60{}^{ \circ} +(4x - 80) {}^{ \circ} = 180{}^{ \circ}  \\  \\  \\   \implies \tt \: 120{}^{ \circ} - 80{}^{ \circ} + 4x = 180{}^{ \circ}  \:  \:  \:  \:  \:  \: \\  \\  \\  \implies  \tt 40{}^{ \circ} + 4x = 180{}^{ \circ}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \\  \implies \tt \: 4x = 180{}^{ \circ} - 140{}^{ \circ} \:  \:  \:  \:  \:  \:  \\  \\  \\  \tt \implies \: 4x = 140{}^{ \circ} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \\  \implies \tt \: x =  \frac{140}{4}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \\  \tt \implies \: { \boxed{ \mathfrak{ \pmb{ \pink{x = 35}}}}} \bigstar \\  \\  \\

Answer:

x = 35

Step-by-step explanation:

Sum of angles of triangle = 180°

  • 60 + 60 + 4x - 80 = 180
  • 40 + 4x = 180
  • 4x = 140
  • x = 140/4
  • x = 35°

Julie gives 7 pieces of candy to each of her friends. If Julie gives all of her candy away, which amount of candy could have bee
True [87]
To find the answer to this problem, you just need to figure out which total amount of candy is divisible by 7.

161/7=23
<span>162/7=23.1428571429
</span>145/7=<span>20.7142857143
128/7=</span><span>18.2857142857

Obviously, Julie cannot give a fraction of an amount of candy to someone.  So that rules out that she had 162, 145, or 128 pieces of candy.  

The only amount of candies that Julie could have that is divisible by 7 is 161 candies, which means that 161 is your answer.</span>

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(1). 2 8 10 4
Klio2033 [76]
Hello!

You can solve this by plugging 1 into g(x) and plugging the result into h(x).

g(x) = 2x
g(1) = 2(1)
g(1) = 2

h(x) = 2x + 4
h(g(1)) = 2(2) + 4
h(g(1)) = 4 + 4
h(g(1)) = 8

Answer:
<span>(h ∘ g)(1) = 8</span>

Answer:

1/3

Step-by-step explanation:

The only way it could be less than 9 is if the second cube is either 1 or 2. The probability of either of those outcomes is 2/6, simplified to be 1/3
