The answer is = (3-2)x4 = (3-2)=1, 1x4=4
Answer:
m∠A=90°, m∠B=60°, m∠C=30°
Step-by-step explanation:
step 1
Verify if the triangle ABC is a right triangle
Applying the Pythagoras theorem

----> is true
therefore
Is a right triangle
m∠A=90°
Find the measure of angle C
sin(C)=AB/BC
substitute
sin(C)=6/12=1/2
so
m∠C=30°
Find the measure of angle B
we know that
m∠C+m∠B=90°------> by complementary angles
so
m∠B=90°-30°=60°
Answer:
$7
Step-by-step explanation:
1. 1/5 = 2/10
2. 2/10 = 20%
3. 20% = 0.2
4. 35 x 0.2 = 7
