Given that a || b, m∠2 = 63° and m∠9 = 105°.
Now, all the angles are as follows:
m∠5=
m∠2 = 63° [vertically opposite angle]
m∠7=
m∠9=105° [vertically opposite angle]
m∠8=
180°-m∠9=180°-105°=75° [Supplementry angles, m∠8+m∠9=180°]
m∠10=
m∠8=
180° [vertically opposite angle]
m∠6=
m∠8=75° [ Alternate angles]
m∠3=
m∠6=75° [vertically opposite angle]
m∠1=
180°-(m∠2+m∠3)=180°-(63°+75°)=42° [as m∠1+m∠2+m∠3=180°]
m∠4=
m∠1=42° [vertically opposite angle]
m∠11=m∠4=42° [ Alternate angles]
m∠13=
m∠11=42° [vertically opposite angle]
m∠12=
180°-m∠11=180°-42°=138° [as m∠8+m∠9=180°]
m∠14 =
m∠12=138° [vertically opposite angle]
Answer:
uh I'm not so sure but
Step-by-step explanation:
it might be 1664
Answer:
the answer is for sure is x=-1-2
A scalene triangle is a triangle where all the three sides are in different lengths, and all the three angles are of different measures.
<h3>How to illustrate the triangle?</h3>
Your information is incomplete. Therefore, an overview will be given. In geometry, an isosceles triangle is thd triangle that has two sides that are of equal length.
The sum of all the interior angles is always equal to 180 degrees. The equilateral triangle is a triangle where all three sides have the same length and 60° each.
The radius of a circle is any of the line segments from its center to its perimeter.
