Try drawing a line between ∠a and <span>∠b and label it Z or z. Connect the line with D.
z=b+c
d=z+a
d=a+b+c
I hope this helped.</span>
Answer:
0.375%
Step-by-step explanation:
The number of people that have an A are 3 females and 5 males. When you add that that together you get 8. So 3/8 is the ratio you get. When you divide 3 by 8, you receive .375 as an answer.
Answer:
diagram of truss with some angles missing
What are the measures of the angles located at positions a, b, & c? Note: the figure is symmetrical on the vertical through angle b.
The large triangle is an isosceles triangle. The two angles on the base are equal. Angle a = 35°
We now know two angles in the largest triangle. The third angle, angle b must add to these to make 180°.
35° + 35° + b = 180°
b = 180° - 70°
b = 110°
We now know two angles in a quadrilateral. The two unknown angles, including angle c are equal. All four angles add up to 360°.
2c + 110° + 120° = 360°
2c = 360° - 230°
2c = 130°
c = 65°
Step-by-step explanation:
Having a fraction as a factor in a multiplication is operated by multiplying the numerator by any whole number and leaving alone the denominator, or if you multiply fractions, then you multiply numerators and denominators separately.
So in this case you have 8 halved apples, that is, 8 times one half apples:
8*(1/2)
this we solve by multiplying the whole number 8 times the numerator 1, and dividing by the denominator:
= 8*1/2
= 8/2
so you have 8 halved apples, which means
= 4
4 apples

Answer:
yes
Step-by-step explanation:
If two angles of one triangle match two angles of another, all three angles must be the same, and the triangles are similar. Here, angles A and D are congruent, and angles C and F are congruent. Hence ΔABC ~ ΔDEF.
