Answer:

69°

Step-by-step explanation:

Sum of angles in a triangle is 180°.

Moreover, because the marked lines are parallel, the third angle of the triangle (first two being 62° and Θ) is equal to 49°

That gives us:

\Theta = 180^\circ - 49^\circ - 62^\circ = 69^\circ

Each question in the test was worth an equal number of points. Chris answered 6 questions incorrectly. How many questions did th
Art [367]

Using mathematical operations and ratios, the number of questions that the other kids answered incorrectly was <u>1 each</u>.

<h3>What are the mathematical operations?</h3>

The mathematical operations include these four basic operations - addition, subtraction, multiplication, and division.

These mathematical operations and ratios, which set one value equal to another, are used to solve mathematical problems.

<h3>Data and Calculations:</h3>

The number of questions = 20

Marks awarded to each question = 3 points

Average incorrect answers by Chris = 6

Average performance = 50%

Above average performance = 90%

Incorrect answers by other students = 10% (1 - 90%)

<h3>Incorrect performance ratios:</h3>

Chris = 50%

Four students = 10%

= 5 : 1

Chris' ratio = 5/6

Four students = 1/6

The number of questions that the four other students answered incorrectly was <u>1 question</u> (6/50% x 10%) or (6 x 1/6).

Thus, the other kids answered <u>1 question</u> each incorrectly.

<h3>Question Completion:</h3>

A test has 20 questions. The test awards 3 points if the answer is correct and takes away 1 point if the answer is incorrect. Five students took the test, but four of the five students perform above average (90%). Chris, an average student (50%), answered 6 questions incorrectly. How many questions did the other kids answer incorrectly?

Find the measure of angle C of a triangle ABC, if: m∠A = ∝, m∠B = 2∝
Effectus [21]

Answer:

The measure of ∠ C is 180°-3∝

Step-by-step explanation:

We are given a ΔABC

∠A = ∝

∠B = 2∝

Angle sum property of triangle : The sum of all angles of triangle is 180° is called angle sum property of triangle

So, ∠A+∠B+∠C=180°

∝+2∝+∠C=180°

3∝+∠C=180°

∠C=180°-3∝

Hence the measure of ∠ C is 180°-3∝
