Answer:

53.8°

Step-by-step explanation:

Use cosine law

67² = 72² + 76² - 2(72)(76)cosX

cosX = 719/1216

X = 53.75190075

Answer:

Step-by-step explanation:

Since we know the three sides and no angle is known, we would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes

SR² = SQ² + QR² - 2(SQ × QR)CosQ

67² = 76² + 72² - 2(76 × 72)CosQ

4489 = 5776 + 5184 - 2(5472)CosQ

4489 = 10960 - 10944CosQ

10944CosQ = 10960 - 4489

10944CosQ = 6471

CosQ = 6471/10944

CosQ = 0.59

Q = Cos^(- 1)0.59

Q = 53.8° to the nearest tenth

Complete the statements. If both expressions have the same value after substituting and simplifying two different values for the
8_murik_8 [283]

When both expressions have the same value,  then they are equal to each other.

<h3>What is an equivalent expression?</h3>

The equivalent is the expressions that are in different forms but are equal to the same value.

Consider the expressions 5 + 8k and 8k + 5.

Using k = 3

5 + 8k = 8k + 5

5 + 8(3) = 8(3) + 5

5 + 24 = 24 + 5

29 = 29

Using k = 5

5 + 8k = 8k + 5

5 + 8(5)= 8(5) + 5

5 + 40 = 40 + 5

45 = 45

<u>Complete question:</u>

Consider the expressions 5 + 8k and 8k + 5. Determine why the expressions are equivalent.

Using k = 3 5 + 8k 8k + 5 5 + 8(3) 8(3) + 5 5 + 24 = 29 24 + 5 = 29

Using k = 5 5 + 8k 8k + 5 5 + 8(5) 8(5) + 5 5 + 40 = 45 40 + 5 = 45

Complete the statements.

If both expressions have the same value after substituting and simplifying two different values for the variable, then they are.

The value of both expressions when k = 3 is and when k = 5 is 45, so the expressions are.

If m ∥ n, m∠1 = (5x + 12)°, and m∠2 = (7x – 16)°, what is m∠3?
asambeis [7]

Answer:

98°

Step-by-step explanation:

m∠1 = m∠2

5x + 12 = 7x - 16; substitute the given

2x = 28

x = 14

m∠2 + m∠3 = 180; supplementary angles

82 + m∠3 = 180

m∠3 = 180 - 82

m∠3 = 98 degrees
