Answer:

Step-by-step explanation:

The angle left to b is

90° - a

= 90° - 53°

= 37°

So now

< b + 37° = 180° ( being linear pair )

< b = 180° - 37°

< b = 143°

Which set of side lengths can be used to construct a triangle?

valentina_108 [34]

9514 1404 393

Answer:

D 75 inches, 55 inches, 45 inches

Step-by-step explanation:

The sum of the two shortest sides must exceed the length of the longest side. This is only the case for choice D.

A. 45+55 < 110

B. 45+45 = 90 . . . . needs to be greater, not equal

C. 35+45 < 100

D. 45+55 > 75 . . . . will form an obtuse triangle

Suppose that a travel bureau claims that the trees in a forest are 83 feet tall on average, With a standard deviation of 2 feet

valentinak56 [21]

Answer:

Step-by-step explanation:

Given mean = 84,

Standard deviation = 2,

Sample 64,

95% confidence interval: z = 1.96

Applying empirical rule , means that 95% of data fall within two standard deviations.

ME = = 0.49

Rounding this to 0.5

CI = 83.5< mean < 84.5

Outside of this range= x ≤ 83.5 and ≥ 84.5

Solve each system of equations by graphing. y = 2x y = x + 1

yawa3891 [41]

Step-by-step explanation:

The system of linear equations are , (i) y = 2x and (ii) y = x + 1 . We will find some coordinates and then we will plot its graph. The point where both Graphs will meet will be the solution of the graph .

• Finding coordinates of Equⁿ (i) :-

Step 1 : Put x = 0 :-

$\tt y = 2x = 2(0) = \red{0}$

Step 2: Put x = 1 :-

$\tt y = 2x = 2(1) = \red{2}$

$\boxed{\begin{array}{c|c|c} \bf x & \tt 0 &\tt 1 \\ \bf y &\tt 0 & \tt 2 \end{array}}$

_________________________________

• Finding coordinates of equⁿ (ii) :-

Step 1 : Put x = 0 :-

$\tt y = x + 1 = 1 + 0 = \red{1}$

Step 2: Put x = 1 :-

$\tt y = x + 1 = 1 + 1 = \red{2}$

$\boxed{\begin{array}{c|c|c} \bf x & \tt 0 &\tt 1 \\ \bf y &\tt 1 & \tt 2\end{array}}$

Now plot these points on the graph Taking appropriate scale . Refer to the attachment in graph . From graph the Solution is (1,2) .
