Vertical angles are congruent, so
107=3x-4
3x=111
x=111/3=37°
1150, i’m pretty sure that’s it!
Answer:Solve. 2a + 3b = 5 6= a -5 a = 4 b = -1 1 a = 6 b=1 a=6 6 = -1 a=4 6 = 1
Step-by-step explanation:
Answer:
(C) r=5.2 in
Step-by-step explanation:
firstly, we will draw diagram
we know that
centroid divides altitude into 2:1 form
so, we get

now, we can plug
h=7.794


so, option-C...............Answer
Here are the answer: a) R = 3.6 and b) A = 2
Step-by-step explanation:
Given,
R is inversely proportional to A.
R ∝ 
so, R =
-------eq 1 where k is any constant
To find the values of a) R when A = 5 and
b) Value of A when R = 9
Now,
Putting R = 12 and A = 1.5 in eq 1 we get,
12 = 
or, k = 12×1.5 = 18
From eq 1 we get,
R =
--------- eq 2
Now,
a) Putting A= 5 in eq 2 we get,
R =
= 3.6
b) Putting R = 9 in eq 2 we get
R =
or, A =
= 2
