1) 110+30+a = 180
a = 180-140 = 40
Obtuse angled triangle
2) 50+50+C = 180
C=180-100 =80
Acute angled triangle
3) 45+45+b =180
b =180-90 = 90
Right angled triangle
4) 45+60+C = 180
C = 180-105 =75
Acute angled triangle
5) 94+47+b =180
b = 180-141=39
Obtuse angled triangle
6)81+53+a = 180
a =180-134 = 46
Acute angled triangle
7) 38+45+b =180
b = 180-83 =97
Obtuse angled triangle
8) 36+54+C =180
C =180-90 = 90
Right angled triangle.
Answer:
3
Step-by-step explanation:
4(x + 1) + 8 = 24
Subtract 8 from each side
4(x + 1) + 8-8 = 24-8
4(x + 1) = 16
Divide by 4
4(x+1)/4 = 16/4
x+1 = 4
Subtract 1
x+1-1 = 4-1
x=3
Since the measure of angle
is 
The measure of its reference angle = 
=
Now we have to compute the value of 


The value of (
) lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.
So, 

= -1.
Answer:

Step-by-step explanation:
Given

Find a and b
Substitute
for x and y in 



Rewrite as:

The above implies that (a) is correct;
Hence:

So, the equation is:

It would be 50? your adding/increaseing 44.2 centimeters to 16 centimeters because
