85 is the measure of a missing angle
Answer:
Range
Step-by-step explanation:
Range is found by subtracting the highest and lowest point in the dataset
Mode is the number that occurs most frequently in the set
Median is the central number in the dataset when arranged from lowest to highest
Mean is the sum of all the numbers in the dataset divided by how many numbers there are.
For example, take this list of numbers: 10, 10, 20, 40, 70.
The mean (also known as average) is found by: 10 + 10 + 20 + 40 + 70 / 5 = 30.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
Answer:
The value of x is 5
Step-by-step explanation:
<em>The measure of the </em><em>exterior angle</em><em> at one vertex of a triangle equals the </em><em>sum of the measures of the two opposite interior angles</em><em> to this vertex</em>
In ΔQRS
∵ ∠QRS is an exterior angle of the triangle at vertex R
∵ ∠PQR and ∠RPQ are the opposite interior angles of vertex R
→ By using the rule above
∴ m∠QRS = m∠PQR + m∠RPQ
∵ m∠QRS = (10x - 10)°
∵ m∠PQR = (2x + 1)°
∵ m∠RPQ = (3x + 14)°
→ Substitute them in the equation above
∴ 10x - 10 = 2x + 1 + 3x + 14
→ Add the like terms in the right side
∵ 10x - 10 = (2x + 3x) + (1 + 14)
∴ 10x - 10 = 5x + 15
→ Subtract 5x from both sides
∵ 10x - 5x - 10 = 5x - 5x + 15
∴ 5x - 10 = 15
→ Add 10 to both sides
∵ 5x - 10 + 10 = 15 + 10
∴ 5x = 25
→ Divide both sides by 5 to find x
∴ x = 5
∴ The value of x is 5
