Answer: (8, 2)
Step-by-step explanation:
up and right are positive, so we need to add the motion made to the left for the x coordinate and subtract the motion made upward from the y coordinate.(3 + 5, 11 - 9) = (8, 2)
The polygons are said to be similar if and only if the ratio of the measures of their corresponding sides are equal. If we are to establish the equation by the definition given above that would be,
15/10 = 60/x
The value of x from the equation is 40. Hence, the side measures 40.
ANSWER: 40
The answer is the last choice.
Step-by-step explanation:
log243(81)=4/5
81=243^4/5
Option B
Answer:
(A) Angles in equilateral triangle are congruent
Step-by-step explanation:
From the figure, it can be seen that in triangle ABD, 
which means that all the sides of the triangle are congruent and by the definition of equilateral triangle, ΔABD will be an equilateral triangle.
Therefore, Using the property that Angles in equilateral triangle are congruent, we can find the value of x.
Thus, option A is correct.
Answer:
2_2 x3 cos x/2 + 1/ 2 4- x 2 dx
