You will need one 1,000 box cube and 2 flat ones
Answer:
D
Step-by-step explanation:
The inscribed angle x whose vertex lies on the circle and whose sides are chords of the circle is one half the measure of the intercepted arc, thus
x = 0.5 × 102° = 51° → D
Answer:
Step-by-step explanation:
Triangles by definition have 3 sides. If the sides are corresponding then it is beneficial to us if they are the same length as well. If all 3 sides in one triangle are equal in length to the corresponding sides in another triangle, then the triangles are congruent by SSS (side-side-side). This is the case for us. Side EC is corresponding and congruent to side AC; side CD is corresponding and congruent to side CB; side ED is corresponding and congruent to side AB.
Answer: X = -4
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
1) 3/5=9/x (cross multiply<span>)
3x=5(9)
3x=45
x=15
2) </span>2/4=x/12 (cross multiply<span>)
</span> 2(12)=4x
24=4x
<span> 6=x
</span>3) 10/x=5/9 (cross multiply<span>)
10(9)=5x
90=5x
18=x
</span>
4) 5/6=x/18
5(18)=6x
90=6x
x=15
