Answer:
as of my calculation it is, a acute angle to the looks of it. so it is therefore 25.
Step-by-step explanation:
the missing angle is 
° .
<u>Step-by-step explanation:</u>
Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :
We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c :
⇒ 
In question we have following parameters as :
Putting these value in we get :
⇒
⇒ 
⇒ 
⇒ 
⇒ °
Therefore , the missing angle is ° .
Answer:
191
Step-by-step explanation:
the rule is +4 so 11+45*4=191 (45 is the number not including the first one)
191 is the answer
Basically find the eqatuions of the lines that produce the shaded reigon
so find the lines first
we notice taht they must be inequalities
the upward line is dotted so it must have > or <
ok, hum the slope seems to be -3
the y intercept is 1 so the euaiton is y_-3x+1
the blank is the inequality
ok, test a point
(0,0) is in it
0_-3(0)+1
0_1
0<1
so it is y<-3x+1
secondn line
solid line so ≤ or ≥
slope of 2
y intercept of -1
y_2x-1
(0,0) is a possible solution
test it
0_2(0)-1
0_-1
0≥-1
so the equations are
y<-3x+1 and y≥2x-1
a. the system is y<-3x+1 and y≥2x-1
b. a solution is (0,0) because it is in the shades reigon which is the intersection of the 2 inequalities
