The answer is 15 cm. Hope I could be of help! ; )
Equations : Tiger Algebra gives you not only the answers, but also the complete step by step ... 5 x 2+5 x −5=0 ... 5x^2+5x-5=0 ... Parabola, Finding the Vertex: ... Root 2 at {x,y} = { 0.62, 0.00} ...
Y=58
Y+14/6=12
Cross multiply to solve
So y+14=72 then subtract 14 so
Y=58
Answer:
p = 56.7°
n = 123.3°
Step-by-step explanation:
The sum of linear pair angles is 180° because, because a linear pair angles, are angles formed by two intersected lines and the angle of a straight line is 180°.
Then your first equation is:
n + p = 180°
The second equation can be formulated with the information given:
"angle n is 10 more than twice the measure of angle p."
n = 10 + 2p
Replacing in the first equation:
10 + 2p + p = 180°
3p = 170°
p = 56.7°
n = 123.3°
