Answer:

ZA is acute

Step-by-step explanation:

Here, we are interested in knowing what can be concluded given the information in the question.

Firstly, a definition was given for angles which are less than 90. Afterwards, a given value was set for the angle.

Since the given angle is less than 90, we can identify that that the value of the unknown angle is acute, which gives our answer

Please help ill give brainiest answer

Answer:

1: AAS, RQC 2: ASA, SRP

Step-by-step explanation:

(1) We are shown that two angles and one side are congruent in the order of AAS. Make sure you write the letters in terms of the corresponding angles. The angles and sides are congruent because the problem labels it for us. For example, B,A,C=R,Q,S. Answers: AAS, RQC.

(2) We are shown that two angles and one side are congruent in the order of ASA. Make sure you write the letters in terms of the corresponding angles again. For example, P,Q,R=P,S,R. The angles are congruent because the problem labels it for us. Side PR is congruent to side PR by reflexive property. Answers: ASA, SRP.

I hope this helped :) Good luck

How are the solutions to the inequality -3x>18 different from the solutions to -3x>18 ?

Novay_Z [31]

Answer:

x < -6

Step-by-step explanation:

-3x > 18

Divide both sides by -3

-3x/-3 < 18/-3

Note : in inequalities when both sides are divided by negative or minus, the inequality sign changes.

Therefore

x < -6

There's no difference as the equations are the same

Assuming the conditions regarding the motion represented in the graph remain the same, determine the acceleration of the object

vovikov84 [41]

(a)

We can see that

this is a straight line

and this is the graph of velocity

we know that

acceleration is the derivative of velocity

so, slope of curve of velocity is acceleration

so, we will find slope of this line

We can select any two points

(0,4) and (5,7)

we can use slope formula

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug points

$m=\frac{7-4}{5-0}$

$m=0.6$

we know that slope of line is always constant irrespective of any value of t

so, acceleration will always be same irrespective of any value of t

so, we will get acceleration

$a(t)=0.6m/s^2$ ............Answer

(b)

we can see that acceleration is constant

and we know that

derivative of constant is always 0

so, instantaneous rate of acceleration at t=10s is 0........Answer
