<h2>Answer:</h2>

<u>For question 1 the answer is 95 mm Hg per year and for question 2 the answer is approximately 147mm Hg</u>

<h2>Step-by-step explanation:</h2>

The equation give to us for the systolic blood pressure is given as y = x + 95. If we look at the graph and the equation there is an increase of 95 mmHg for each value of x which is the age so we can say that an increase of 95mm Hg is recorded. Then for the second part of the question if we again look at the graph we can see that the age is given in x axis and blood pressure in y axis. Value of x at 42 touches the y axis on 147 approximately which is the required blood pressure for given age.

Priya noticed in the last activity that between the 2 triangles, you only need to know 4 angles to show that they are similar. S

Answer:

Please find attached a drawing of the triangles ΔRST and EFG showing the angles

The angle on ΔEFG that would prove the triangles are similar is ∠F = 25°

Step-by-step explanation:

In order to prove that two triangles are similar, two known angles of each the triangles need to be shown to be equal

Given that triangle ∠R and ∠S of triangle ΔRST are 95° and 25°, respectively, and that ∠E of ΔEFG is given as 90°, then the corresponding angle on ΔEFG to angle ∠S = 25° which is ∠F should also be 25°

Therefore, the angle on ΔEFG that would prove the triangles are similar is ∠F = 25°.
