Can you put the question in English?
Step-by-step explanation:
<h2>
Sum of two complementary angle is 90°</h2><h2 /><h2>
so. </h2><h2>
<R+<S =90°</h2><h2>
12x-3+7x-2=90°</h2><h2>
19x-5=90°</h2><h2>
19x=95°</h2><h2>
X= 5</h2>
<h2>
<R= 60-3=57°</h2>
Whats the equation to the question
Answer:
234ft²
Step-by-step explanation:
Surface of the triangular prism
= ab+3bh
= (6ft×13ft)+(3×13ft×4ft)
= 78ft²+156ft²
= 234ft²
Hence, the surface area of the given triangular prism is 234ft².
