Answer: Triangles can also be classified by their angles. In an acute triangle all three angles are acute (less than 90 degrees). A right triangle
Step-by-step explanation:Classification of triangles according to the length of their sides · Isosceles triangle · Equilateral triangle · Scalene Triangle.
Answer:
‹A = 141°
‹B = 28°
‹C = 11°
*These angles are rounded to the nearest whole*
Step-by-step explanation:
Because you are only given sides you can find an individual angle measures with the inverse law of cosines.
Remember the side opposite of the angle corresponds to that angle.
a² = b² + c² - 2bc cos(A) →
A = cos⁻¹ (a² - b² - c² / -2bc)
b² = a² + c² - 2ac cos(B) →
B = cos⁻¹ (b² - a² - c² / -2ac)
c² = a² + b² - 2ab cos(C) →
C = cos⁻¹ (c² - a² - b² / -2ab)
Answer:
y = 4x - 26
Step-by-step explanation:
The change in y is 4 when the change in x is 1.
So the slope is change in y/change in x = 4/1 = 4
y = mx + b
30 = 4(14) + b
30 = 56 + b
b = - 26
Therefore, y = 4x - 26
Answer:
b) 1.34
Step-by-step explanation:
The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:
For the largest 9%, the score is 100% - 9% = 91% = 0.91
From the normal distribution table, the z score that corresponds to 0.91 is 1.34
Answer:
x = 5.25
y = 7.5
Step-by-step explanation:
Since line 1.5 is parallel to line x which is parallel to line y
then 2/(2+5) = 1.5/x
2x = 7(1.5)
2x = 10.5
x = 5.25
Similarly, 2/(2 + 5 + 3) = 1.5/y
2y = 10(1.5)
2y = 15
y = 7.5
