The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
5% of 1000 is 5 * 1000 / 100 = 5000 / 100 = 50.
Inside a triangle, all inside angles add up to 180°
So, add the two angles:
26.4°+33.7°=60.1°
180°-60.1°=119.9°
b=119.9°
Answer:
(2, 9)
Step-by-step explanation:
y=2x+5
x=2 ⇒ y=2*2+5=4+5=9
so the point is (2, 9)
