Answer:
∠ABC = 60°
Step-by-step explanation:
All angles in equilateral triangles are equal.
all angles in triangles added together = 180°
180°/3 = 60°
All angles in equilateral triangles are equal to 60°.
Answer:
Slope of line B: 1/3
Step-by-step explanation:
To find a slope perpendicular to another slope, you take its negative reciprocal.
Therefore, line B will have a slope of 1/3 because -3 -> -1/3 -> 1/3
Answer:
10.8
Step-by-step explanation:
3^0=1
2*1=2
23.6-2=21.6
21.6/2=10.8
626. tangent because adjacent and hypotenuse are given. tan= o/a
tan(9)= .1584
o/.1584 = 3954/1
cross multiply.
o= .1584 * 3954
o= 626
