Answer:
x=90
y=67
Step-by-step explanation:
as the line that bisects the vertical angle of isosceles triangle perpendicularly bisects the base
so x=90
and sum of all sides of triangle is 180 so
90+23+y=180
therefore,y=67
answer:
<h2>
X = 90°</h2><h2>
y = 67°</h2>
Solution,
We know ,
AB = AC
<B = <C
< A + <B + <C = 180° ( sum of angle in triangle)
or, 46 + y + y = 180°
or, 46 + 2y = 180°
or, 2y = 180° - 46°
or, 2y = 134
or, y = 134/2
y = 67°
The value of y is 67°
Now, In ∆ ABD
<BAD + <B + < ADB = 180°
or, 23 + 67 + X = 180°
or, 90 + X = 180
or, X = 180 - 90
X = 90°
The value of X is 90°
Hope this helps ...

Answer:
49 minutes
Step-by-step explanation:
Given :
Start time = 1:39 p. M
Return time = 2.28 p. M
Time spent Walking dog = difference between the start time and return time
Return time - start time
(2:28 p.m - 1:39p.m) = 49 minutes
Hence, Tiffany spent 49 minutes walking her dog
53= -19z+5+7z
53= -12z+5 (combine -19z and 7z)
48= -12z. ( subract 5 on both sides)
-4=z. (divide by -12 both sides)
