Step-by-step explanation:
- right triangle is A right triangle or right-angled triangle is a triangle in which one angle is a right angle
- acute triangle is An acute triangle is a triangle with three acute angles. An obtuse triangle is a triangle with one obtuse angle and two acute angles
- obtuse triangle is An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It's impossible for a triangle to have more than one obtuse angle.
Answer:
C
Step-by-step explanation:
They values have a proportional relationship, as x increases by 4, y increases by five, giving a slope of 5/4. You can use the slope and a point given (I'll use (1,5)) in the equation y=mx+b to find the y-intercept, so solving for 5=5/4(1)+b you get 4.75 as your y-intercept. Simplified to slope intercept form y-5=5/4(x-1) is equal to our equation, so the answer is C.
Answer:
14) (C) 8√2 km
15) (C) 225°
Exercise 15.17 (D) 8.7 km
Step-by-step explanation:
14)
d² = 8² + 8² = 64 + 64 = 128
d = √128 = 8√2 km
15) 180° + 45° = 225°
Exercise 15.17
QR² = 10² - 5² = 100 - 25 = 75
QR = √75 = 5√3 = 8.7 km

The answer you want is 'The function is a direct variation' because at the same rate y changes then x will change along with it.
Hope that helps you.
