Answer:
Step-by-step explanation:
we have the triangle GHJ
If the segment side GH is equal to the segment JH
then
The triangle GHJ is an isosceles triangle
Remember that
An isosceles triangle has two equal interior angles and two equal sides
so
m∠G=m∠J
we have
m∠G=(7x+5)°
m∠J=(x+47)°
equate the equations
(7x+5)°=(x+47)°
Solve for x
Answer:
12a^2+18ab-6ac+25a-3b+c
Step-by-step explanation:
Answer:
m∠2 = 57°
Step-by-step explanation:
From the triangle given in the picture,
By applying triangle sum theorem in ΔABC,
m∠BAC + m∠ABC + m∠BCA = 180°
90° + m∠2 + 33° = 180°
m∠2 + 123° = 180°
m∠2 = 180° - 123°
m∠2 = 57°

Here we can use the Thales Theorem , according to which here if the ratio of JK and KL will be equal to the ratio of MN and ML then the lines KM and JN will be parallel .So ,
JK/KL = MN/ML
22.5/25 = 18/20
225/250 = 18/20
9/10 = 9/10
<u>H</u><u>ence </u><u>here </u><u>since </u><u>the </u><u>ratios </u><u>are </u><u>equal</u><u> </u><u>the </u><u>lines</u><u> </u><u>will </u><u>be </u><u>parallel</u><u>.</u>
