We need some sort of diagram to see what they are. Is there any way to say that ac = db? Either equal angles or equal lines.
x + 3 = 3x - 19 Add 19
x + 3 + 19 = 3x Subtract x
21 = 2x
x = 21 / 2
x = 10.5
ac = 10.5 + 3
x = 13.5
Answer:
Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.
The last one
yes
im right u can ask google
Answer:
false
Step-by-step explanation:
correct me if this is wrong, but it's actually x>1
Answer:
y<5
Step-by-step explanation:
y+8 < 13
y < 13-8
y < 5
