Answer:

Step-by-step explanation:
θ = 228° = (228°)×(π/180° radians/degree) = 228/180 radians
= 19/15 radians
≈ 1.266...(repeating) radians
6z-7z/5=3
(30z-7z)/5=3
30z-7z=15
23z=15
z=15/23
Answer:
2. z=8
3.2x=16
5.distributive property
7.Addition property of equality
i'm not 100%ly sure so if it's wrong sorry and pls don't report mine i'm just trying to help not get my answer deleted:)
Let x be the <span>length of each of two congruent sides.
</span>The triangle will be аcute if:
x² + x² > 8²
2x² > 64
x² > 32
x > √32
x > 5.657
So, the smallest possible length of one of two congruent sides have to be 5.7 cm (<span>to the nearest tenth)</span>
