Answer:X=4
Step-by-step explanation:
Congruent triangles method
AB/DB=BC/EC
10-x+x/10-x=3+2/3
10/10-x=5/3
30=50-5x
30-50=-5x
-20=-5x
X=4
You get them either thrift or wrong
A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
You can use pythagorean theorem and square 1.5 and 6 and those added together is the hypotenuse (the slope) squared. the answer is approximately 6.2
Answer:
∠ABC= 45°
Step-by-step explanation:
∠ABC= ∠BCD (alt. ∠s, AB//CD)
(2x +15)°= (3x)°
2x +15= 3x
3x-2x= 15 <em>(</em><em>-2x </em><em>on </em><em>both </em><em>sides)</em>
x= 15
Substituting the value of x:
∠ABC
= ∠BCD
= [3(15)]°
= 45°
