1 dag = 10 g
1 dg = 0.1 g
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>
2. 7 to 5 and a total of 96 in this radio there is a total of 12 so divide 96 by 12 to find out how many sets of 7:5 are in 96 stickers
96/12= 8
It's wants large stickers
7×8= 56 large stickers
