Answer:
x=27°
Step-by-step explanation:
we know that
<u><em>The Triangle Exterior Angle Theorem</em></u>, states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles
step 1
Find the measure of angle PLM
we know that
m∠PLM+m∠LPM=m∠PMN ----> by Triangle Exterior Angle Theorem
we have
m∠LPM=x°
m∠PMN=2x+72°
substitute
m∠PLM+x=2x+72°
m∠PLM=2x-x+72°
m∠PLM=x+72°
step 2
Find the measure of angle x
we know that
3x+m∠PLM=180° ----> by supplementary angles (form a linear pair)
we have
m∠PLM=x+72° (see step 1)
substitute
3x+x+72°=180°
4x=180°-72°
4x=108°
x=27°
Answer:
x = 1
Step-by-step explanation:
-4v+5x=17 give that (x,-3) is the solution
so x coordinate is = x (unknown)
y coordinate is = -3
substitute the value of y in -4y+5x=17
therefore
-4(-3)+5x=17
12+5x=17
5x=17-12
5x=5
x=5/5
x=1
It is 100 times more than 0.8 and 10 times more is 8. to find it out u have to go 2 places to the left and u will get 100
3x + 1.50y = 39
12 Roses 2 Carnations
3(12) + 1.50(2) = 39
36 + 3 = 39
39=39
