Find the angles in the image
Rama09 [41]

Answer:

  • a) 36°, b) 36°, c) 72°

Step-by-step explanation:

<h3>Given:</h3>
  • PT║VW and SR is transversal
  • m∠PQR = 36°
<h3>To find:</h3>
  • a) m∠SQT
  • b) m∠QRW
  • c) m∠PRV
<h3>Solution</h3>

a) ∠SQT is vertical with ∠PQR and therefore has equal measure

  • m∠SQT = 36°

b) ∠QRW is corresponding angle with ∠SQT and therefore has equal measure

  • m∠QRW = 36°

c) m∠PRV = m∠PRQ as marked equal

  • m∠PRV +m∠PRQ + m∠QRW = 180° as straight angle
  • m∠PRV*2 = 180° - 36°
  • m∠PRV*2 =144°
  • m∠PRV = 144°/2
  • m∠PRV = 72°

How to solve 2×4÷3+5
Nataly [62]

You will need to follow order of operations, which states that operations must be completed in the following order: parentheses, exponents, multiplication and division, and then addition and subtraction.


In this case, there are no parentheses and no exponents, so we will start with the multiplication and division:

2 \cdot 4 \div 3 + 5 = (2 \cdot 4 \div 3) + 5

\Bigg(\dfrac{8}{3} \Bigg) + 5


Now, we will finish by doing addition and subtraction:

\Bigg(\dfrac{8}{3} \Bigg) + 5 = \dfrac{8}{3} + \dfrac{15}{3}

\dfrac{8 + 15}{3}

\boxed{\dfrac{23}{3}}


Our answer is \boxed{\dfrac{23}{3}}.

A fair number cube is rolled. What is the probability that a number less than 4 is rolled?
patriot [66]

Answer: B) 1/2

There are six sides labeled 1,2,3,4,5,6. We want values that are less than 4, so we want values from the set {1,2,3} which represents half of the list. In other words, we have 3 ways of getting what we want (1 or 2 or 3) out of 6 ways total (1,2,3,4,5,6) to have 3/6 = 1/2
